From Mathematical Foundation to Open Experimental Program: A Revised Unified Account of the Total Wave Modified Schrödinger Equation (TWMSE)

Abstract

This paper presents a revised unified account of the Total Wave Modified Schrödinger Equation (TWMSE), a proposed deterministic collapse framework in which quantum state reduction is investigated as a possible dynamical consequence of interaction between a system wavefunction and observer fields associated with physical interactions. The purpose of this revision is to distinguish clearly between mathematical structures that have been explicitly formulated, consequences that follow from the minimal written dynamics, and stronger experimental proposals that remain to be derived. A central result is that a spatially homogeneous scalar collapse term can modify the global amplitude of a quantum state but cannot, by itself, generate spatial localization or branch selection. After normalization, the common scalar factor cancels from the spatial probability distribution. Likewise, a spatially homogeneous multiplicative metric can restore a conserved physical norm but does not by itself produce a measurable spatial probability bias. The paper also corrects the treatment of the time dependent metric. Conservation of the physical norm requires the full time dependent metric condition, G˙+ℏi(H†G−GH)=0, rather than the time independent pseudo Hermitian relation alone. For the minimal scalar TWMSE model, the corresponding metric compensates exactly for the non Hermitian amplitude evolution, while also revealing a long time invertibility issue when the collapse functional possesses a nonzero mean. These results change the status of several experimental signatures proposed in the earlier unified TWMSE account. In particular, a nonzero Sorkin parameter, a second harmonic in Mach Zehnder interferometry, associated detection time estimates, and an already established branch dependent history bias are not treated in this revised paper as derived predictions of the minimal homogeneous TWMSE dynamics. They are retained instead as open derivation and experimental targets that require a genuinely spatially structured, operator level, or branch sensitive probability dynamics. The two system history experiment is consequently reformulated as a falsifiability target. A completed TWMSE model would need to demonstrate mathematically how different observer field histories could produce different normalized outcome statistics for systems having the same final standard quantum state, while remaining distinguishable from ordinary Hamiltonian evolution, decoherence, systematic effects, and competing collapse models. The paper further identifies the principal mathematical requirements for completing the framework, including branch sensitive collapse dynamics, existence and consistency of the time dependent metric, derivation of the physical probability law, strong coupling phase dynamics, accumulated interference and memory, multi particle consistency, no signalling, relativistic completion, conservation laws, parameter identification, and derivation or revision of the earlier interferometric proposals. This paper represents the author's current technical position on these questions and supersedes the experimental interpretation of the earlier technical unified account, Zenodo DOI 10.5281/zenodo.19537024, where those claims exceed what follows from the minimal written dynamics. The earlier technical paper remains part of the public development record. Its plain English companion, Zenodo DOI 10.5281/zenodo.19537305, likewise remains part of that record and should be read in light of the present revision. The objective of this revised account is therefore narrower but stronger: to state explicitly what TWMSE presently derives, what remains conditional, what remains open, and what must be demonstrated before the framework can yield a distinctive, normalized, causal, and experimentally testable prediction. Revision notice: This publication represents the author's current technical position on the experimental status of TWMSE. It supersedes the interpretation of experimental claims in Zenodo DOI 10.5281/zenodo.19537024 where those claims exceed what follows from the minimal homogeneous dynamics. The plain English companion to that earlier account, Zenodo DOI 10.5281/zenodo.19537305, should likewise be read in light of this revision. Both earlier records remain publicly available as part of the development history.
