含克尔介质高Q腔内“单模场—单原子”系统的腔场谱

Abstract

研究了充满克尔介质的高Q腔和二能级原子系统的腔场谱,讨论了克尔效应对谱结构的影响.发现克尔介质与腔场的耦合会使数态光场腔场谱中的原共振谱线分裂成频差为2χ的双线,且双线的'中心频率”随初态光子数的增加而远离共振频率.当初始光场为光子数态的叠加态时,腔场谱在强耦合情况下一般为多峰结构,峰的个数随着初始平均光强的增大而增加.

“两原子—双模腔场”系统的腔场谱

高云峰, 冯健, 宋同强

研究了存在偶极相互作用的两等同原子与双模腔场共振相互作用双光子过程的腔场谱,研究发现,当两模初态都为光子数态或相干态时,两模腔场谱之间有很强的相互影响,在两模场强相同时,两划的光谱结构也相同,且在强场下呈现三峰结构;当两模初态场强不同时,较强的一模出现简单的单峰结构,而较弱模光谱中三峰的距离随另一模光子数的增加而增大。当两模均为压缩真空态时,在强场下得到经典共振荧光谱,且两模腔场谱之间的相互影响很弱。

Why Modern Physics Still Thinks Like Newton: A χ‑Ontological Analysis of Algebraic Substantialism in 21st‑Century Theoretical Frameworks

Anatolii Mukha

The ZEBTS‑SUPER 10.0 framework establishes χ‑Reality as a constructive, spectrally compact, ontologically invariant engine of existence. Reality is generated by successive χ‑acts under constraints defined by the χ‑Universal Invariants Iχ. The components of the χ‑engine — admissibility Aχ, boundary geometry ∂χ, gradient bias Gχ, collapse Πχ, spectral compactness Cχ = const, operator engine χ^, global χ‑Spectral Matrix Mχ, and invariant backbone Iχ — form a unified mechanism that constructs, stabilizes, and integrates physical structures. Potentiality is defined by Aχ. Interfaces by ∂χ. Actualization by Gχ. Existence by Πχ. Stability by Cχ. Construction by χ^. Coherence by Mχ. Rigidity by Iχ. Spacetime emerges as (∂χ, Πχ). Time is collapse rank. Geometry is spectral shift Δχ. Gravity is Gχ + Δχ. Fields are boundary patterns. Constants are invariants. The macroscopic world is the stabilized trace |ψ(global)⟩. The χ‑engine does not evolve within a background; the background is constructed by the χ‑engine. Empirical phenomena — interference, decoherence, entanglement, curvature, gravity, field behavior, temporal ordering, stability of constants — are patterns of χ‑acts constrained by Iχ. The χ‑Universal Invariants ensure spectral rigidity, collapse convergence, gradient coherence, boundary stability, operator consistency, matrix invariance, and ontological completeness. ZEBTS‑SUPER 10.0 provides the ontological reconstruction of reality: Reality = stabilized χ‑spectral structure under {Aχ, ∂χ, Gχ, Πχ, Cχ = const, χ^, Mχ, Iχ} Existence is χ‑constructed. Actuality is χ‑stabilized. Geometry is χ‑spectral. Time is χ‑collapse rank. Constants are χ‑invariants. The world is the stabilized trace of χ‑acts.

The χ‑Absolute and the Zero‑Entropy Background Topological Structure: A Fundamental Ontological Framework for Physics

Anatolii Mukha

Abstract This work develops a unified ontological and mathematical framework for fundamental physics based on the Zero‑Entropy Background Topological Structure (ZEBTS) and the four irreducible structural components of χ‑reality: the χ‑metric, χ‑symplectic form, χ‑topology, and χ‑information. Within this framework, physical observables are formulated as χ‑tensors, and the algebra of observables arises from χ‑symplectic geometry rather than postulated commutation relations. The resulting χ‑commutator is a geometric tensor encoding the curvature of χ‑symplectic structure, while χ‑operators inhabit a χ‑manifold equipped with χ‑metric, χ‑symplecticity, χ‑curvature, χ‑topology, and χ‑informational complexity. The theory establishes a complete χ‑spectral formalism, where χ‑measurement is a χ‑topological projection, χ‑superselection emerges as a theorem of χ‑topology and χ‑information, and χ‑entropy is defined through χ‑spectral and χ‑operator entropies. χ‑dynamics is formulated as a χ‑Hamiltonian flow on the χ‑operator manifold, incorporating χ‑geodesics, χ‑topological currents, and χ‑informational gradients. The χ‑Absolute is introduced as the structural limit Iχ→∞, representing the boundary of physically realizable configurations and the ontological attractor of χ‑dynamics. A central result of the framework is that Special Relativity (STR), General Relativity (GTR), and Quantum Phenomena (QP) arise as χ‑projections of the unified χ‑structure: STR as the χ‑metric projection, GTR as the χ‑geometric projection, and QP as the χ‑symplectic projection. Particles appear as χ‑topological defects of χ‑spectrum, and fields arise as χ‑modes of χ‑operators. The theory yields concrete experimental predictions, including χ‑modulations in the CMB, χ‑topological signatures in large‑scale structure, χ‑dispersion of gravitational waves, χ‑entropy bounds in cosmology, and χ‑geometric distortions in astrometric data. Overall, the χ‑framework provides a coherent, mathematically rigorous, and physically testable unification of geometry, topology, quantization, information, and cosmology. It demonstrates that the structure of physical reality is not imposed but emerges from the intrinsic χ‑geometry of being, with ZEBTS as the realized background and χ‑Absolute as the structural limit of the Universe.

q形变偶相干光场与[I]型三能级原子相互作用中场的压缩效应

张慧慧

建立了q形变偶相干场与巨型三能级原子相互作用的非线性理论,求得了在相互作用表象中薛定谔方程的形式解及其在该形态下的期望值。数值计算结果表明,q形变对相互作用中场压缩效应有着很强的调制能力,这是q形变非线性行为对量子相干性干扰以及对量子特性影响的内在反映。当q→1时,恢复为普通的偶相干光场线性理论。
