The SQC Invariant in Hydrogenic Theory II: Exact Recovery of the Two Einstein-B Invariants from B12B_{12}B12 and B21B_{21}B21 extends the Part I A21A_{21}A21-sector result into the stimulated-transition sector by working in the standard Einstein convention defined with radiation energy density per unit ordinary frequency, ρν\rho_\nuρν. In that convention, the spontaneous-emission relation A21=ISQC(g1g2)f12ν2A_{21}=I_{\mathrm{SQC}}\left(\frac{g_1}{g_2}\right)f_{12}\nu^2A21=ISQC(g2g1)f12ν2 is combined with the standard Einstein relations A21=8πhν3c3B21,g1B12=g2B21.A_{21}=\frac{8\pi h\nu^3}{c^3}B_{21},\qquad g_1B_{12}=g_2B_{21}.A21=c38πhν3B21,g1B12=g2B21. From these, the paper derives two exact recovery formulas for the same electromagnetic time invariant from the two stimulated coefficients separately: ISQC(B12)=8πhc3νB12f12,ISQC(B21)=8πhc3νB21(g1/g2)f12.I_{\mathrm{SQC}}^{(B_{12})}=\frac{8\pi h}{c^3}\frac{\nu B_{12}}{f_{12}}, \qquad I_{\mathrm{SQC}}^{(B_{21})}=\frac{8\pi h}{c^3}\frac{\nu B_{21}}{(g_1/g_2)f_{12}}.ISQC(B12)=c38πhf12νB12,ISQC(B21)=c38πh(g1/g2)f12νB21. Both reduce identically to ISQC=2πe2ε0mec3=7.42165600145×10−22 s,I_{\mathrm{SQC}}=\frac{2\pi e^2}{\varepsilon_0 m_e c^3} =7.42165600145\times10^{-22}\ \text{s},ISQC=ε0mec32πe2=7.42165600145×10−22 s, using CODATA 2022 values as published by NIST. The paper also recovers a second exact stimulated-sector cofactor, νB12f12=νB21(g1/g2)f12=e24ε0meh=c38πhISQC,\frac{\nu B_{12}}{f_{12}} = \frac{\nu B_{21}}{(g_1/g_2)f_{12}} = \frac{e^2}{4\varepsilon_0 m_e h} = \frac{c^3}{8\pi h}I_{\mathrm{SQC}},f12νB12=(g1/g2)f12νB21=4ε0mehe2=8πhc3ISQC, showing that both BBB-channels collapse onto the same invariant structure when written with the correct degeneracy weighting. A central interpretive point is that the bare identity B12=B21B_{12}=B_{21}B12=B21 is not generally exact in the standard Einstein formalism; the exact relation is g1B12=g2B21g_1B_{12}=g_2B_{21}g1B12=g2B21. Equality of the two BBB coefficients occurs only in the special case g1=g2g_1=g_2g1=g2, or when one works with suitably degeneracy-weighted coefficients. Hilborn’s review is especially useful here because it carefully distinguishes conventions based on energy density per unit angular frequency, per unit ordinary frequency, and related alternative definitions, where factors of 2π2\pi2π and ccc can otherwise be confused. Overall, the paper places the stimulated Einstein coefficients into the same SQC-style invariant framework previously established for A21A_{21}A21, showing that the stimulated and spontaneous sectors recover the same fixed electromagnetic constant while preserving the standard degeneracy structure of Einstein’s original formalism.
The SQC Invariant in Hydrogenic Theory II: Exact Recovery of the Two Einstein-B Invariants from B12B_{12}B12 and B21B_{21}B21 extends the Part I A21A_{21}A21-sector result into the stimulated-transition sector by working in the standard Einstein convention defined with radiation energy density per unit ordinary frequency, ρν\rho_\nuρν.

Description The SQC Invariant in Hydrogenic Theory III: The Exact Connection Between the Two SQC Scretching Invariants completes a three-part investigation into the structure of radiative invariants in hydrogenic systems by establishing a precise algebraic equivalence between two previously derived SQC quantities. Building directly on earlier results, this work demonstrates that the spontaneous-emission time constant and the stimulated-radiation cofactor are not independent constructs but rather complementary expressions of the same underlying electromagnetic content. The first invariant, associated with spontaneous emission, governs the Einstein A-coefficient sector and encodes the characteristic radiative decay timescale. The second invariant, tied to stimulated processes, governs the Einstein BBB-coefficient sector and captures the coupling strength to external radiation fields. Using the standard Einstein relations in the ordinary-frequency convention, the paper derives an exact proportionality linking these two quantities through a simple conversion factor involving fundamental constants. This result shows that JSQC=c38πh ISQC, ISQC=8πhc3 JSQC,J_{\text{SQC}} = \frac{c^3}{8\pi h} \, I_{\text{SQC}}, \quad I_{\text{SQC}} = \frac{8\pi h}{c^3} \, J_{\text{SQC}},JSQC=8πhc3ISQC,ISQC=c38πhJSQC, establishing that the two invariants are algebraically interchangeable representations connected by the spontaneous-to-stimulated transition framework originally formulated by Albert Einstein. In this interpretation, the distinction between spontaneous and stimulated emission is not a separation of constants, but a redistribution of the same invariant structure across different radiative regimes. The analysis carefully adheres to standard conventions, including the ordinary-frequency formulation of Einstein coefficients and established degeneracy relations. Consistency with modern physical constants is maintained through the use of National Institute of Standards and Technology CODATA 2022 values, and the treatment aligns with established literature such as the review by Robert C. Hilborn. Overall, this paper clarifies that the SQC invariants do not introduce new physics, but instead reveal a hidden algebraic unity within the standard radiative formalism. By explicitly connecting the AAA- and BBB-coefficient sectors, it provides a compact and conceptually transparent framework for understanding how spontaneous and stimulated processes arise from the same fundamental electromagnetic structure.
Description The Stimulated Einstein Branch of the Scretching Quantum Chain: B12,B21B_{12}, B_{21}B12,B21, Degeneracy-Normalized Equality, and New SQC Invariants extends the Scretching Quantum Chain (SQC) framework into the domain of stimulated radiative processes, completing the structural picture initiated in earlier work on spontaneous emission. This paper systematically incorporates the Einstein BBB-coefficients—governing absorption and stimulated emission—into the SQC formalism, demonstrating that they obey the same invariant structure already identified in the spontaneous AAA-sector. Building from the established hydrogenic SQC state vector, which includes transition dipole strength ∣μ12∣2|\mu_{12}|^2∣μ12∣2, oscillator strength f12f_{12}f12, and the Einstein coefficients A21,B21,B12A_{21}, B_{21}, B_{12}A21,B21,B12, the work derives two new stimulated-branch invariants. These are constructed by combining the previously published spontaneous-emission invariant with the standard Einstein reciprocity relations. The resulting quantities, IB,21=B21 ν(g1/g2)f12,IB,12=B12 νf12,I_{B,21} = \frac{B_{21}\,\nu}{(g_1/g_2)f_{12}}, \quad I_{B,12} = \frac{B_{12}\,\nu}{f_{12}},IB,21=(g1/g2)f12B21ν,IB,12=f12B12ν, are shown to collapse to a single constant, KB=e24ε0meh,K_B = \frac{e^2}{4\varepsilon_0 m_e h},KB=4ε0mehe2, revealing a unified invariant structure across both stimulated emission and absorption processes. A key conceptual result is the clarification of degeneracy effects: while the raw Einstein relation g1B12=g2B21g_1 B_{12} = g_2 B_{21}g1B12=g2B21 reflects intrinsic asymmetry, the paper shows that the stimulated coefficients become exactly equal when expressed in degeneracy-normalized form. This normalization exposes a deeper symmetry within the radiative system, aligning both coefficients with the same invariant constant. The framework is validated through hydrogen Lyman-series transitions, confirming numerical closure using previously published datasets. The analysis remains fully consistent with the standard radiative theory originally developed by Albert Einstein, and does not introduce new physical laws. Instead, it reorganizes known relationships into a deterministic invariant chain that unifies spontaneous emission, stimulated emission, and absorption within a single algebraic structure. Overall, this work completes the extension of the SQC formalism into the stimulated regime, demonstrating that all three radiative processes share a common invariant foundation. The result is a more comprehensive and internally consistent framework for understanding radiative transitions in hydrogenic systems.
This paper extends the Scretching Quantum Chain (SQC) far beyond its previously developed applications to the Lamb shift, hyperfine structure, and Zeeman effect by introducing two new invariant-based branches of the framework. First, it develops an SQC treatment of the Stark effect, covering both linear and quadratic regimes, and derives new SQC–Stark invariants, a parameter-free electric-field sensitivity coefficient, and a complete Stark multiplet sum rule. Second, it expands the SQC into the Einstein B-coefficient domain, showing that the absorption and stimulated-emission coefficients, B12 and B21, together generate two new dimensionless invariants, Ψ1 and Ψ2. Among these, Ψ2 is especially significant because it yields a direct experimental determination of oscillator strength f12 from B12 alone, presented here as a new result not found in standard quantum-optics treatments. The paper also introduces a symmetric invariant, Xsym, that captures the degeneracy structure of both lower and upper states simultaneously, thereby extending the algebraic reach of the SQC formalism while preserving exact reduction to the standard SQC law in the zero-perturbation limit. Using six hydrogen transitions from the Lyman and Balmer series, the study provides numerical verification against NIST data together with full graphical validation. Overall, the work positions the SQC as a broader deterministic radiative framework capable of unifying spontaneous emission, stimulated processes, and field-induced spectral perturbations under one constant-sloped invariant structure.
This paper derives the Scretching–Schrödinger Equation (SSE) in full theoretical detail from the ordinary Schrödinger equation, transition dipole theory, oscillator-strength formalism, Einstein coefficient theory, and the Maxwell–Scretching experimental closure. The derivation begins with the time-dependent Schrödinger equation, separates the stationary time-independent form, and then connects quantum-state evolution to spectroscopic observables through the transition dipole moment, oscillator strength, spontaneous-emission coefficient, and absorption-emission closure relations. Within this framework, the SQC spectroscopic invariant is introduced as Kν=2πe2ε0mec3K_{\nu}=\frac{2\pi e^{2}}{\varepsilon_{0}m_{e}c^{3}}Kν=ε0mec32πe2, which links electromagnetic coupling, electron mass, light speed, and frequency-dependent spectroscopic behavior. The paper then derives the SSE closure constant, KSSE=3ℏ(4.32×10−9)2meK_{\mathrm{SSE}}=\frac{3\hbar(4.32\times10^{-9})}{2m_{e}}KSSE=2me3ℏ(4.32×10−9), as the coefficient that transfers the Maxwell–Scretching experimental closure into the quantum wave-equation formalism. The resulting Scretching–Schrödinger Equation is formulated as a constrained wave equation in which the Hamiltonian contains an additional spectroscopic correction operator, VSQCV_{\mathrm{SQC}}VSQC. This operator represents the SQC-imposed correction that connects ordinary quantum-mechanical evolution with experimentally recoverable spectroscopic closure behavior. The derivation also corrects two important formal issues. First, the Hamiltonian is treated properly as an unbounded self-adjoint operator acting on a suitable dense domain in Hilbert space, rather than as an ordinary finite matrix or unrestricted algebraic operator. Second, the hydrogen 1s→2p1s\rightarrow2p1s→2p radial transition integral is written in its corrected form, 276 a035\frac{2^{7}\sqrt{6}\,a_{0}}{3^{5}}35276a0, rather than the incorrect expression 282 a035\frac{2^{8}\sqrt{2}\,a_{0}}{3^{5}}35282a0. Together, these corrections strengthen the mathematical foundation of the SSE and ensure that the spectroscopic derivation remains consistent with standard quantum mechanics, hydrogenic transition theory, and the Maxwell–Scretching closure framework [1–5].
This section applies the C∗C^*C∗-algebraic Schrödinger–Scretching Equation (SSE) to the hydrogen atom. The ordinary hydrogen Hamiltonian, H^H=−ℏ22me∇2−e24πε0r,\hat{H}_{H} = -\frac{\hbar^{2}}{2m_{e}}\nabla^{2} - \frac{e^{2}}{4\pi\varepsilon_{0}r},H^H=−2meℏ2∇2−4πε0re2, is extended by introducing a Scretching Quantum Chain spectroscopic correction operator. The hydrogen SSE Hamiltonian is written as H^SSE,H=H^H+V^SQC,H,\hat{H}_{\mathrm{SSE},H} = \hat{H}_{H} + \hat{V}_{\mathrm{SQC},H},H^SSE,H=H^H+V^SQC,H, where V^SQC,H=ℏKν(g1g2)ν^ 2f^.\hat{V}_{\mathrm{SQC},H} = \hbar K_{\nu} \left(\frac{g_{1}}{g_{2}}\right) \hat{\nu}^{\,2}\hat{f}.V^SQC,H=ℏKν(g2g1)ν^2f^. Thus, H^SSE,H=H^H+ℏKν(g1g2)ν^ 2f^\boxed{ \hat{H}_{\mathrm{SSE},H} = \hat{H}_{H} + \hbar K_{\nu} \left(\frac{g_{1}}{g_{2}}\right) \hat{\nu}^{\,2}\hat{f} }H^SSE,H=H^H+ℏKν(g2g1)ν^2f^ where KνK_{\nu}Kν is the Scretching Quantum Chain invariant, Kν=2πe2ε0mec3≈7.4216560×10−22 s.K_{\nu} = \frac{2\pi e^{2}}{\varepsilon_{0}m_{e}c^{3}} \approx 7.4216560\times 10^{-22}\ \mathrm{s}.Kν=ε0mec32πe2≈7.4216560×10−22 s. In the C∗C^*C∗-algebraic formulation, the hydrogen observable algebra evolves through the SSE automorphism group, αtSSE,H(A)=USSE,H(t)†AUSSE,H(t),\alpha_{t}^{\mathrm{SSE},H}(A) = U_{\mathrm{SSE},H}(t)^{\dagger} A U_{\mathrm{SSE},H}(t),αtSSE,H(A)=USSE,H(t)†AUSSE,H(t), with USSE,H(t)=exp(−iℏH^SSE,Ht).U_{\mathrm{SSE},H}(t) = \exp\left( -\frac{i}{\hbar} \hat{H}_{\mathrm{SSE},H}t \right).USSE,H(t)=exp(−ℏiH^SSE,Ht). The corresponding hydrogen SSE derivation is δSSE,H(A)=iℏ[H^SSE,H,A].\delta_{\mathrm{SSE},H}(A) = \frac{i}{\hbar} \left[ \hat{H}_{\mathrm{SSE},H},A \right].δSSE,H(A)=ℏi[H^SSE,H,A]. Substituting the hydrogen SSE Hamiltonian gives δSSE,H(A)=iℏ[H^H,A]+iℏ[ℏKν(g1g2)ν^ 2f^,A].\delta_{\mathrm{SSE},H}(A) = \frac{i}{\hbar} \left[ \hat{H}_{H},A \right] + \frac{i}{\hbar} \left[ \hbar K_{\nu} \left(\frac{g_{1}}{g_{2}}\right) \hat{\nu}^{\,2}\hat{f}, A \right].δSSE,H(A)=ℏi[H^H,A]+ℏi[ℏKν(g2g1)ν^2f^,A]. Therefore, the ordinary hydrogen derivation is extended by an additional spectroscopic SQC derivation: δSSE,H(A)=δH(A)+δSQC,H(A).\delta_{\mathrm{SSE},H}(A) = \delta_{H}(A) + \delta_{\mathrm{SQC},H}(A).δSSE,H(A)=δH(A)+δSQC,H(A). The SQC Einstein-rate scale associated with a hydrogen transition is ASQC=Kν(g1g2)ν2f.A_{\mathrm{SQC}} = K_{\nu} \left(\frac{g_{1}}{g_{2}}\right) \nu^{2}f.ASQC=Kν(g2g1)ν2f. For the hydrogen Lyman-alpha transition, 2p→1s,2p\rightarrow 1s,2p→1s, the transition wavelength is approximately λLyα≈121.567 nm.\lambda_{\mathrm{Ly}\alpha} \approx 121.567\ \mathrm{nm}.λLyα≈121.567 nm. Thus, νLyα=cλLyα≈2.4661×1015 s−1.\nu_{\mathrm{Ly}\alpha} = \frac{c}{\lambda_{\mathrm{Ly}\alpha}} \approx 2.4661\times 10^{15}\ \mathrm{s}^{-1}.νLyα=λLyαc≈2.4661×1015 s−1. Using the oscillator strength fLyα≈0.4162,f_{\mathrm{Ly}\alpha} \approx 0.4162,fLyα≈0.4162, and the degeneracy ratio g1g2=13,\frac{g_{1}}{g_{2}} = \frac{1}{3},g2g1=31, the SQC Einstein-rate scale becomes ASQC,Lyα=Kν(13)νLyα2fLyα.A_{\mathrm{SQC,Ly}\alpha} = K_{\nu} \left(\frac{1}{3}\right) \nu_{\mathrm{Ly}\alpha}^{2} f_{\mathrm{Ly}\alpha}.ASQC,Lyα=Kν(31)νLyα2fLyα. Numerically, ASQC,Lyα≈6.27×108 s−1.A_{\mathrm{SQC,Ly}\alpha} \approx 6.27\times 10^{8}\ \mathrm{s}^{-1}.ASQC,Lyα≈6.27×108 s−1. This agrees with the known order of magnitude of the hydrogen spontaneous-emission coefficient for the 2p→1s2p\rightarrow 1s2p→1s transition: A2p→1s≈6.26×108 s−1.A_{2p\rightarrow 1s} \approx 6.26\times 10^{8}\ \mathrm{s}^{-1}.A2p→1s≈6.26×108 s−1. For the hydrogen H-alpha transition, 3→2,3\rightarrow 2,3→2, the transition wavelength is approximately λHα≈656.28 nm.\lambda_{\mathrm{H}\alpha} \approx 656.28\ \mathrm{nm}.λHα≈656.28 nm. Therefore, νHα=cλHα≈4.5681×1014 s−1.\nu_{\mathrm{H}\alpha} = \frac{c}{\lambda_{\mathrm{H}\alpha}} \approx 4.5681\times 10^{14}\ \mathrm{s}^{-1}.νHα=λHαc≈4.5681×1014 s−1. The SQC Einstein-rate scale is ASQC,Hα=Kν(g1g2)νHα2fHα.A_{\mathrm{SQC,H}\alpha} = K_{\nu} \left(\frac{g_{1}}{g_{2}}\right) \nu_{\mathrm{H}\alpha}^{2} f_{\mathrm{H}\alpha}.ASQC,Hα=Kν(g2g1)νHα2fHα. Using the appropriate Balmer oscillator-strength and degeneracy weighting gives ASQC,Hα≈4.41×107 s−1.A_{\mathrm{SQC,H}\alpha} \approx 4.41\times 10^{7}\ \mathrm{s}^{-1}.ASQC,Hα≈4.41×107 s−1. This is consistent with the expected order of magnitude for a hydrogen Balmer 3→23\rightarrow 23→2 radiative transition. The hydrogen verification therefore shows that the Schrödinger–Scretching Equation can reproduce standard hydrogen spectroscopic rate scales when the transition frequency, oscillator strength, and degeneracy ratio are correctly inserted into the SQC Hamiltonian correction. In this form, the SSE does not replace the ordinary hydrogen Hamiltonian; rather, it embeds the known hydrogen spectrum into a broader operator-based spectroscopic Hamiltonian: H^SSE,H=−ℏ22me∇2−e24πε0r+ℏKν(g1g2)ν^ 2f^\boxed{ \hat{H}_{\mathrm{SSE},H} = -\frac{\hbar^{2}}{2m_{e}}\nabla^{2} - \frac{e^{2}}{4\pi\varepsilon_{0}r} + \hbar K_{\nu} \left(\frac{g_{1}}{g_{2}}\right) \hat{\nu}^{\,2}\hat{f} }H^SSE,H=−2meℏ2∇2−4πε0re2+ℏKν(g2g1)ν^2f^ This establishes the hydrogen atom as a first verification system for the C∗C^*C∗-algebraic SSE. The Lyman-alpha and H-alpha examples demonstrate that the SQC correction term can be connected to experimentally meaningful atomic transition-rate scales while preserving the ordinary quantum-mechanical Hamiltonian structure, unitary evolution, and C∗C^*C∗-algebraic derivation law.
This paper develops an advanced unified description of the hydrogen atom wavefunction across three major theoretical levels: nonrelativistic quantum mechanics, relativistic quantum mechanics, and the Scretching–Schrödinger Equation framework. The study begins with the standard Schrödinger hydrogen wavefunction, where the electron state is represented as a complex probability amplitude labeled by the quantum numbers nnn, lll, mlm_lml, and msm_sms. It then advances to the relativistic Dirac treatment, where the scalar wavefunction is replaced by a four-component spinor labeled by nnn, κ\kappaκ, and mjm_jmj, thereby incorporating spin, relativistic energy corrections, and the natural appearance of fine-structure splitting. The central contribution of the paper is the extension of the hydrogen atom into the Scretching–Schrödinger Equation (SSE) framework, where the ordinary Schrödinger structure is preserved but constrained by a deterministic spectroscopic closure condition from the Scretching Quantum Chain (SQC) and Maxwell–Scretching Chain (MSC). In this formulation, a valid hydrogen wavefunction must not only satisfy the wave equation but must also reproduce the full physical chain ε→f→∣μ∣2→A21→Kν,\varepsilon \rightarrow f \rightarrow |\mu|^2 \rightarrow A_{21} \rightarrow K_{\nu},ε→f→∣μ∣2→A21→Kν, linking molar absorptivity, oscillator strength, transition dipole moment, Einstein spontaneous-emission coefficient, and the SQC invariant. The invariant Kν=2πe2ε0mec3=7.42165600145×10−22 sK_{\nu}=\frac{2\pi e^2}{\varepsilon_0 m_e c^3} =7.42165600145\times 10^{-22}\ \text{s}Kν=ε0mec32πe2=7.42165600145×10−22 s is derived from first principles and treated as the fixed spectroscopic time-scale anchor of the hydrogen SQC closure. The paper verifies the SQC formulation against NIST hydrogen spectral data for the Lyman series (n=2–4)(n=2–4)(n=2–4) and Balmer series (n=3–7)(n=3–7)(n=3–7), obtaining relative errors no larger than 2.7×10−42.7\times 10^{-4}2.7×10−4, with the remaining discrepancy attributed to rounding limits. It also derives the corrected radial transition integral for the 1s→2p1s\rightarrow 2p1s→2p transition, Ir0=1.2902662 a0,I_{r0}=1.2902662\,a_0,Ir0=1.2902662a0, and uses this value to support the deterministic connection between hydrogen wavefunctions, transition moments, oscillator strengths, and Einstein coefficients. The manuscript further develops the hydrogen SSE Hamiltonian in C*-algebraic form, extends the wavefunction treatment to isotope-corrected protium, deuterium, and tritium, and demonstrates that KνK_{\nu}Kν remains invariant under isotope substitution. Fine-structure effects—including Lamb-shift corrections, hyperfine splitting, and Zeeman perturbations—are examined as higher-order refinements within the SSE context rather than violations of the underlying SQC invariant. Finally, the paper maps the full SQC-to-MSC projection, showing how quantum oscillator strength projects upward into macroscopic electromagnetic observables such as absorption, refractive behavior, dielectric response, and radiative transition strength. The result is a deterministic, parameter-free quantum–electromagnetic hydrogen framework in which NRQM, RQM, SSE, SQC, and MSC are treated as connected layers of the same physical closure chain.
