This record contains three papers that together establish the axiomatic foundation of Potential-Field Theory (Shichanglun / Zhendonglun), a complete dynamical framework that derives all classical gravitational phenomena from a single first principle: the modulation of frequency by the potential field. ——————————————————Paper 1: "Potential-Field Theory:

Kinetic theory and classical limit for real scalar quantum field in curved spacetime [PDF]
, 2018 Starting from a real scalar quantum field theory with quartic self-interactions and nonminimal coupling to classical gravity, we define four equal-time, spatially covariant phase-space operators through a Wigner transformation of spatially translated ...

A Field-Theoretic Gravitodynamic Framework Consistent with General Relativity
Reports in Advances of Physical SciencesWe present a covariant field-theoretical model of gravitation based on a structural analogy with classical electrodynamics. The theory employs a four-potential formulation and introduces dynamic gravitational fields, including a gravitomagnetic component

All things retarded: radiation-reaction in worldline quantum field theory
Journal of High Energy Physics, 2022 We exhibit an initial-value formulation of the worldline quantum field theory (WQFT) approach to the classical two-body problem in general relativity.

Gravitational Dynamics—A Novel Shift in the Hamiltonian Paradigm
Universe, 2021 It is well known that Einstein’s equations assume a simple polynomial form in the Hamiltonian framework based on a Yang-Mills phase space. We re-examine the gravitational dynamics in this framework and show that time evolution of the gravitational field ...

JOURNAL OF ADVANCES IN PHYSICS, 2021 Expansion of the universe is a divine fact in the glorious Quran. The accelerated expansion of the universe is one of the physics mysteries and challenges. This article is a try to find an answer to this ambiguity. A simple fusion and merging of the Newton, Einstein and quantum field equations were carried out to clarify this topic.

Universe, 2019 We briefly review the current status of nonlocal gravity (NLG), which is a classical nonlocal generalization of Einstein’s theory of gravitation based on a certain analogy with the nonlocal electrodynamics of media.

Mathematical Theory of Classical Fields and General Relativity [PDF]
, 1992 The subject of Classical Field Theory has received relatively little attention from both mathematicians and theoretical physicists. The former look at it primarily from the perspective of Quantum Mechanics, namely, as subject of the elusive task of quantization.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
