A Two-Channel Model of Quantum Decoherence with Passive Coherence Revival: Spectral-Gap Dynamics with Falsifiable Revival Threshold

Key Points

The study aims to establish a two-channel model of quantum decoherence that incorporates revival dynamics and distinguishes itself from common models.
Developed two theorems regarding norm conservation and revival thresholds.
Determined predictions related to revival amplitude and delay as a function of coupling.
Analyzed the impact of bath spectral density on revival time.
Monotonic revival amplitude observed with increasing coupling strength.
Revival delay tau_r approximates 1/kappa regardless of environmental factors.
Provided a distinctive revival timescale relevant to future quantum decoherence studies.

Abstract

Two Theorems (Norm Conservation at zero coupling; Revival Threshold kappa*rhoₑnv > Gamma) plus two Predictions (P1: monotonic revival amplitude in coupling; P2 KILL SHOT: revival delay tauᵣ ~ 1/kappa independent of bath spectral density). The two-channel structure with spectral-gap field Delta (x) governs the competition between projection pressure and environmental coupling. The bath-independent revival timescale is the discriminating prediction distinguishing the framework from any standard decoherence model. Inherits from Paper 0 (axioms A3, A4, A6) ; reframed physics-first for Physical Review A submission after Entropy desk-reject.
