On the Nature of Quantum Phenomena

Abstract

It is shown that a coherent understanding of all quantized phenomena, including those governed by unitary evolution equations as well as those related to irreversible quantum measurements, can be achieved in a scenario of successive nonequilibrium phase transitions, with the lowest hierarchy of these phase transitions occurring in a ``resonant cavity'' formed by the entire matter and energy content of the universe. In this formalism, the physical laws themselves are resonantly-selected and ordered in the universe cavity in a hierarchical manner, and the values of fundamental constants are determined through a Generalized Mach's Principle. The existence of a preferred reference frame in this scenario is shown to be consistent with the relational nature of the origin of physical laws. Covariant unitary evolution is shown to connect smoothly with the reduction of wavefunction in the preferred frame during quantum measurement. The superluminal nature of quantum processes in the lowest hierarchy coexists with the universal speed limit obeyed by processes in higher hierarchies. A natural quantum-to-classical transition is also obtained which is stable against the diffusive tendency of the unitary quantum evolution processes. In this formalism a realistic quasi-classical ontology is established for the foundations of quantum mechanics.

A Realist Interpretation of the Quantum Measurement Problem

Xiaolei Zhang

A new, realist interpretation of the quantum measurement processes is given. In this scenario a quantum measurement is a non-equilibrium phase transition in a ``resonant cavity'' formed by the entire physical universe including all its material and energy content. Both the amplitude and the phase of the quantum mechanical wavefunction acquire substantial meaning in this picture, and the probabilistic element is removed from the foundations of quantum mechanics, its apparent presence in the quantum measurement process is viewed as a result of the sensitive dependence on initial/boundary conditions of the non-equilibrium phase transitions in a many degree-of-freedom system. The implications of adopting this realist ontology to the clarification and resolution of lingering issues in the foundations of quantum mechanics, such as wave-particle duality, Heisenberg's uncertainty relation, Schrodinger's Cat paradox, first and higher order coherence of photons and atoms, virtual particles, the existence of commutation relations and quantized behavior, etc., are also presented.

Rethinking the Hierarchy: On the Structural Relation Between Quantum and Classical Theories

Alessandro Sergi, Agostino Migliore, ANTONINO MESSINA

Quantum mechanics is among the most successful physical theories, yet its formulation and empirical testing rely on classical structures. Following Lev Landau and Niels Bohr, this reliance is not merely pragmatic: quantum observables acquire empirical meaning only relative to classical reference frames, and, in practice, quantization starts from classical models. At the same time, the two domains display forms of mutual irreducibility: intrinsically quantum features (that is, spin and exchange statistics) have no counterpart in the phase-space ontology of classical point-particle mechanics, while classical trajectory chaos does not arise straightforwardly from unitary quantum evolution in closed systems. A hierarchy is commonly established between classical and quantum theories, namely, a claim of ontological and explanatory priority according to which quantum mechanics is fundamental and classical mechanics is only a limiting case. This claim is less secure than is often assumed; therefore, the traditional hierarchy deserves to be examined. In this paper, we argue that a quantum–classical framework provides an effective and structurally faithful representation of empirically accessible physical systems in regimes where quantum and classical degrees of freedom coexist within a single, consistent effective dynamical description. To give this point of view a firm theoretical basis, we discuss the quasi-Lie formal structure underlying quantum–classical hybrid dynamics, with applications ranging from gravity and condensed matter to open, driven systems in biology and complex media.

Reference Frames and Degree-of-Freedom Filtering:A Unified Paradigm for Classical Mechanics, Relativity and Quantum Mechanics

Haiqing Wan

Abstract Fundamental discrepancies exist among the foundational postulates of classical mechanics, relativity and quantum mechanics, leaving long-standing open physical puzzles including the origin of the arrow of time, quantum measurement collapse and the nature of spacetime. This paper proposes a self-consistent unified physical paradigm: the physical essence of a reference frame is the selective filtering of the full degrees of freedom of a system. All classical, relativistic and quantum physical theories constitute effective reduced descriptions of degrees of freedom under specific rules imposed by reference frames. Core phenomena such as temporal irreversibility, wave-function collapse, the constancy of the speed of light and the quantum-classical transition are not fundamental ontological properties of the universe, but emergent effects arising from filtering mappings introduced by finite-bandwidth observers. This work establishes an axiomatic framework for reference frames and degree-of-freedom filtering, defining projection filtering mappings, the principle of vanishing relative degrees of freedom, and the dimensionless filtering ratio. Within this framework, we reconstruct classical mechanics, special and general relativity, quantum decoherence and quantum measurement theory. Three categories of irreversible mechanisms — statistical coarse-graining, environmental partial-trace decoherence and time-domain sampling truncation — are integrated into a single mathematical structure. A universal dimensionless filtering ratio is defined. We clarify that the continuity of the control parameter does not imply that observables must evolve smoothly. Conceptually, the system can exhibit three regimes: quantum superposition, intermediate transition and classical state. Experiments on quantum bits at the Weizmann Institute provide preliminary observational hints, yet further verification is required; no specific form of the response curve is assumed in this paper. Three falsifiable quantitative predictions are put forward, involving attosecond spectroscopy, decoherence of superconducting qubits and cold-atom interferometry. We compare the present paradigm with relational quantum mechanics, QBism and consistent histories, discuss the ontological implications of time, observers and irreversibility, and outline extensions towards quantum gravity and cognitive science.

Quantum Laws and Their Origins: An Exploration Based on Three Foundational Hypotheses

zhigang Ye

Abstract This paper presents an in-depth investigation into quantum effects and the three established principles of quantum mechanics, including the dynamics derived from the development of physical systems—specifically, the reversal of positive and negative energy directions, as well as the density expansion and contraction caused by interactions between energy systems. Additionally, this study introduces a novel theoretical framework that proposes a new scope for understanding quantum phenomena. A truly universal principle must satisfy both Galileo’s principle of relativity and the law of covariance, thereby enabling the identification of global hidden variables or underlying mechanisms behind physical phenomena, and allowing for the explanation and demonstration of the deductive logic and outcomes of all physical processes.Contemporary quantum experiments, evaluated through Bell’s inequality, suggest that quantum mechanics is currently regarded as complete. Furthermore, it is widely accepted that quantum entanglement exhibits uncertainty prior to measurement, with its process being superluminal and non-local. However, the fundamental reasons behind these characteristics—particularly their true physical principles, dynamic behavior, and evolutionary logic—remain inadequately addressed. In fact, current interpretations of quantum mechanics are largely superficial and do not fully incorporate Galilean covariance, indicating an inherent incompleteness.At present, the major frameworks of quantum mechanics—including quantum theory, relativity, quantum field theory, and the Schrödinger equation—are primarily confined to the description of the positive (observable) world. They generally deny the possibility of energy direction reversing into negative energy states or transitioning into a hypothetical negative world. Moreover, they reject the idea that quantum entanglement can occur within the negative world and subsequently return to the positive world, implying oscillatory motion, reciprocation, energy exchange, and superluminal properties.The prevailing interpretation—that the interaction between entangled quanta, involving energy, force, reference frames, and positively entangled particles, constitutes a holistic effect—is insufficient. Specifically, attempting to explain the instantaneous, superluminal, and uncertain nature of quantum effects solely based on dynamics restricted to the positive world domain appears fundamentally flawed. Current quantum mechanical explanations fail to identify the global hidden variables or the underlying mechanisms governing physical phenomena. Furthermore, they cannot account for why quantum entanglement results violate Bell’s inequality.According to Galileo’s law of covariance, quantum mechanics should not be satisfied with partial or limited covariance. Therefore, we propose a new quantum mechanical principle grounded in three hypotheses to address these limitations. Given that energy possesses both positive and negative directional properties, particularly under dynamic conditions where energy direction reverses, the instantaneous density ratio becomes extremely small. This leads to the physical realization of quantum superluminal phenomena. Through the principle of resonance—such as energy direction reversal and quantum entanglement—these phenomena become possible.To satisfy Galilean covariance, it can be inferred that only the reversal of the energy vector direction and transition into the negative world can fulfill such requirements. Due to the potential existence of negative entanglement in negative energy and the reciprocal exchange between the positive and negative worlds, there remains uncertainty regarding the parity of energy increase or spin quantity in returning quanta or systems. Furthermore, experimental observations from phase-locked reverse measurements—where "the jump value of PDV data consistently exceeds the rise"—suggest new physical interpretations involving imaginary numbers and calculus related to energy direction and the negative world. These findings demonstrate the pre-measurement uncertainty of quantum states, as well as the superluminal and non-local nature of quantum processes, thereby supporting the inference of a new foundational theory of quantum mechanics.Finally, the quantum teleportation experiment provides evidence of vector reversals in energy and information transmission, further confirming the existence of superluminal communication.

Quantum Mechanics and Cosmology Arising from the Unobservability of Scale

Paul Michel

We propose that the unobservability of absolute scale constitutes a foundational principle of physics. Starting from the requirement that physical predictions must be invariant under rescalings of the action, we show that only phase-based quantities remain well defined. This requirement uniquely selects a complex amplitude description, leading directly to the structure of quantum mechanics, including linear superposition, Hilbert space, and the Born rule. Within this framework, the classical notion of action loses absolute meaning, and physical observables arise from invariant phase relations. Quantum mechanics is therefore not postulated, but emerges as the minimal consistent description of systems in which scale cannot be directly observed. The formal structure of quantum theory is shown to follow from this principle without additional axioms. We further demonstrate that the same principle implies the existence of a dynamical scale field, which governs the effective quantum scale and connects naturally to cosmological models with a time- dependent Planck mass. In this way, the structure of quantum mechanics and the large-scale dynamics of the Universe are linked through a common origin. This framework provides a unified perspective in which quantum behavior and cosmological evolution arise from a single underlying principle, suggesting a new approach to the relationship between fundamental physics and cosmology.
