Effective Phase-Memory Dynamics of Biophotonic and Biphoton Coherence in Myelinated Axonal Waveguides: A Conservative Model with a Minimal Numerical Demonstration

Marcel Krūger

Recent discussions of photon propagation and biphoton generation in myelinated axons motivate a cautious and testable question: can axonal photonic coherence be represented by a low-parameter phase-memory model without invoking unsupported claims about consciousness, gravity, or fundamental spacetime structure? This manuscript reformulates an earlier Helix-Light-Vortex (HLV)-motivated note into a conservative effective model. Myelinated axons are treated as lossy cylindrical dielectric waveguides supporting guided or quasi-guided electromagnetic modes over finite coherence lengths. Biphoton or biophotonic coherence is represented through first-order and second-order optical correlation functions and a causal phase-memory coordinate. The Spiral-Time/phase-memory layer is used only as a phenomenological diagnostic coordinate for non-Markovian phase drift and dephasing, not as a replacement for quantum optics, electrodynamics, neurobiology, or general relativity. A minimal numerical proof-of-concept is added: stochastic phase trajectories are simulated under a Markovian baseline and a causal memory model. The demonstration shows that a memory term can produce distinguishable coherence-decay, local-rate, phase-variance, and windowed instability signatures under controlled conditions. The simulation is not a biological validation. It only establishes that the proposed observable pipeline can distinguish memory-augmented dynamics from a matched memoryless baseline. The resulting framework is falsifiable: it fails if phase-memory observables do not outperform Markovian dephasing or standard waveguide baselines under matched experimental conditions.

Coherent and squeezed states of light in linear media with time-dependent parameters by Lewis–Riesenfeld invariant operator method

Jeong Ryeol Choi

We investigated coherent and squeezed states of light in linear media whose parameters are explicitly dependent on time by making use of the Lewis–Riesenfeld invariant operator method. Not only the field strengths but also the fluctuations of the fields both in coherent and in squeezed states are decayed with time. The relative noise of the field strengths are calculated in coherent state. Quantum statistical properties of the chaotic field are investigated. We applied our theory to a phenomenological model of the biophoton system and compared the corresponding result of the uncertainty product with that obtained from a previous report.
