This collection explores the fundamental physics concepts that govern how matter and energy interact across the universe. From the invisible forces shaping our daily lives to the complex mechanics driving cosmic phenomena, these studies reveal the underlying rules of reality. Here, we translate cutting-edge research into insights anyone can understand, bridging the gap between abstract theory and tangible discovery.
Every new preprint in this category originates from arXiv, where researchers first share their latest findings with the global community. At Gist.Science, we process each of these submissions to provide both detailed technical summaries and clear, plain-language explanations. This dual approach ensures that whether you are a seasoned physicist or a curious learner, you can grasp the significance of every breakthrough without getting lost in dense equations.
Below are the latest papers in Class-Ph, freshly processed and ready for you to explore.
This paper derives analytic solutions for the longitudinal and transverse components of the vector potential in the Lorenz gauge applicable to arbitrary time-dependent charge-current distributions.
This paper proposes a Schrödinger-like wave equation within a canonical Hamiltonian framework to describe the thermodynamics of a particle in an expanding or contracting 1D box, successfully linking mechanical behavior to entropy production, reproducing the universal quantum of heat conductance, and confirming consistency with quantum mechanics in quasi-static regimes while revealing adiabaticity breakdown under far-from-equilibrium conditions.
This paper introduces a non-Hermitian causal generative model that produces statistically significant temporal correlations invisible to conventional spectral analysis, providing experimentally verified signatures of causal memory in open quantum systems.
This paper investigates electron dynamics in electromagnetic fields beyond the adiabatic approximation using Stormer theory, characterizing the spectrum of orbits as predominantly chaotic or hyperchaotic while highlighting unresolved questions regarding their impact on neutrino mass limits and correlation experiments.
This paper demonstrates that Feynman's proof of the Maxwell equations, when reformulated in a non-quantum relativistic framework with minimal hypotheses, fundamentally relies on the principle that gauge field interactions and their corresponding equations of motion are deducible from the minimal coupling rule.
This paper generalizes the construction of fracton models to phase space by classifying systems with multipole conservation laws and analyzing a new self-dual model that exhibits quasi-periodic orbits, thereby preventing full ergodic exploration of the phase space.
This paper reviews the necessary calculations for constructing a Lyapunov-like functional to analyze the nonlinear stability of both equilibrium and non-equilibrium steady states in thermodynamically isolated and open systems composed of compressible, heat-conducting fluids.
This paper describes a dynamic light scattering setup using diffusing wave spectroscopy, implemented in an undergraduate physics lab at TU Darmstadt, to investigate the dynamics of vertically shaken sand grains and demonstrate the similarity between jamming in athermal granular media and the glass transition in thermally driven molecular systems.
This paper presents a geometric framework for analyzing spatial degrees of freedom and channel strength in antenna systems by linking spectral properties to mutual shadow measures and coupling strength, thereby providing efficient closed-form estimates for modal richness in near-field channels.
This paper introduces a new fixed-point iteration scheme based on the Bidirectional Pulse Propagation Equations to solve nonlinear electromagnetic scattering problems in slab-like geometries with arbitrary material responses, demonstrating its convergence and accuracy through a case study involving mixed fast electronic and slow molecular vibrational responses.
