The Path Integral as TUT Projection: A GMaTT Interpretation of Feynman's Sum Over Histories

Abstract

Abstract Feynman's path integral formulation describes quantum propagation as a sum over all possible paths, weighted by a phase factor e^{iS/ℏ}. The classical path emerges via constructive interference of paths with stationary action. We reinterpret this mechanism within the Generalized Mass as Twisted Time (GMaTT) framework. The phase factor is identified as the accumulated phase difference Δφ of a G₂ root vector rotating around the √α axis. The condition for constructive interference is shown to be equivalent to the TUT (TwistUntwist Threshold) coherence condition |δφ| < √α. We clarify that the TUT window is not a dynamic laboratory filter but a static geometric boundary condition of the phase space. Classical paths are not "chosen" by the particle; they are the trajectories that maintain phase coherence within the TUT threshold during propagation. This provides a geometric origin for the path integral and the principle of least action, grounding Feynman's sum in the pregeometric phase geometry of GMaTT.

- Path Integral Formulation

S. Rajasekar, R. Velusamy

The conventional approach to quantum mechanics begins with the classical Hamiltonian and changes observables to noncommuting operators. Canonically conjugate observables have to be noncommuting operators in order to satisfy the Heisenberg uncertainty principle. The dynamics of a quantum mechanical system is given by the time-dependent Schrödinger equation. In the early 1940s Feynman realized that it would be possible to construct a quantum model using the classical Lagrangian approach (a method closely related to the action integral). Dirac had earlier pointed out that eit times the Lagrangian was analogous to a transformation function for the wave function in which the wave function at one instant could be related to the wave function at a next instant in a time interval of t by multiplying with such an exponential function. Feynman found the exponential phase factor to be the action S which is the time integral of the Lagrangian. Further, he noticed that it was necessary to perform integrals over all space variables at every instant of time to find the transition amplitudes. He developed a way for describing and evaluating the integration using the idea of integral over all paths. In Feynman’s approach, the particles are described using amplitudes calculated along the paths they may or may not follow. These amplitudes behave like waves, their phase changes as the quantum system moves along the path and the amplitudes for all paths superpose and interfere. This interference between all paths is called as sum-over-histories and the resulting amplitude is connected in the same way that the amplitude of a wave function is linked to probability as magnitude-squared.

A physical basis for the phase in Feynman path integration

Garnet N. Ord, J. Anthony Gualtieri, Robert B. Mann

In the path integral formulation of quantum mechanics, the phase factor Exp[iS(x[t])] is associated with every path x[t]. Summing this factor over all paths yields Feynman's propagator as a sum-over-paths. In the original formulation, the complex phase was a mathematical device invoked to extract wave behaviour in a particle framework. In this paper we show that the phase itself can have a physical origin in time reversal, and that the propagator can be drawn by a single deterministic path.

Path Integral Formulation of Quantum Mechanics

Michael T. Strickland

This chapter introduces the path integral formulation of quantum mechanics as a rigorous and systematic alternative to canonical quantization. It begins by defining the transition probability amplitude (propagator) and deriving the path integral by discretizing time and summing over all possible intermediate paths between initial and final spacetime points. The chapter shows the final form of the propagator as a functional integral over all paths, weighted by the exponential of the action. This formulation provides an intuitive understanding that paths near the classical trajectory (which minimizes the action) interfere constructively, dominating the overall amplitude.

Vägintegral för Väteatomen : Lösningar i två och tre dimensioner

Svensson, Anders

The path integral formulation of quantum mechanics generalizes the action principle of classical mechanics. The Feynman path integral is, roughly speaking, a sum over all possible paths that a particle can take between fixed endpoints, where each path contributes to the sum by a phase factor involving the action for the path. The resulting sum gives the probability amplitude of propagation between the two endpoints, a quantity called the propagator. Solutions of the Feynman path integral formula exist, however, only for a small number of simple systems, and modifications need to be made when dealing with more complicated systems involving singular potentials, including the Coulomb potential. We derive a generalized path integral formula, that can be used in these cases, for a quantity called the pseudo-propagator from which we obtain the fixed-energy amplitude, related to the propagator by a Fourier transform. The new path integral formula is then successfully solved for the Hydrogen atom in two and three dimensions, and we obtain integral representations for the fixed-energy amplitude.

The Quantum Extension: C: P(G) → C - Summing Complex Amplitudes over Consistent Paths Gives the Feynman Path Integral for a Free Particle in 4D Minkowski Spacetime

Eliam Raell

This paper completes the Boolean-to-quantum transition. The consistency predicate C, previously taking values in {0,1}, is extended to take values in C. Each consistent path from x to y is assigned amplitude exp(i * tau(path)), where tau is the sum of Minkowski proper times along the path. The propagator K(x,y) is the sum of these amplitudes over all consistent paths.Four experiments confirm that this extension gives quantum mechanics. Phases span the full circle: paths interfere, cancelling and reinforcing. The geodesic (longest chain) maximises the action tau(path), and near-geodesic paths reinforce while off-geodesic paths cancel the stationary phase approximation. The propagator |K|^2 grows with proper time with correlation r=0.84, p=0.036. All twelve pairs analysed show constructive interference with |K|/sqrt(n) greater than 1 in every case.In the continuum limit, K(x,y) converges to the free particle Feynman propagator exp(i * m * tau_proper(x,y)). The action S = proper time emerges from J(2,C) geometry. No physics is assumed. Quantum mechanics emerges from the algebraic structure of distinction.

Derivation II: The Feynman Phase from Foliation Holonomy

Yuri Alcocer

We derive the Feynman path integral weight not as a postulate of quantum mechanics, but as the geometric holonomy of parallel transport on the Update Bundle. The "sum over histories" emerges as the regulator's integration over its sub-ℏ blind spot—the fiber volume it cannot resolve. Key Result: The path integral is the volume calculation of geometric indistinguishability, with interference arising from rank-sorting (constructive for stable geometries, destructive for rank-deficit configurations).
