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 re-evaluates the theoretical model for generating electric power from Earth's rotation via its magnetic field by correcting previously neglected electromagnetic boundary conditions for a moving cylindrical shell, which leads to revised calculations for the induced mechanical force and total power output.
This paper demonstrates how the familiar spacetime symmetry groups, specifically the de Sitter and Poincaré algebras, emerge from the more fundamental relativistic quantum phase space symmetry of the Linear Canonical Transformations (LCT) group through Inönü-Wigner contractions driven by minimum and maximum length scales.
This study experimentally demonstrates that deep-water gravity-wave solitons can coexist with classical linear diffraction, maintaining their longitudinal solitonic character while undergoing transverse reshaping governed by Fresnel laws.
This paper proposes a generalized Newton's cooling law derived from linear irreversible thermodynamics that incorporates cumulative heat exchange to explain the macroscopic Mpemba effect and other anomalous relaxation behaviors through memory-dependent structural evolution.
This paper demonstrates that the mechanical stiffness of an elastic material containing holes can be preserved through the strategic adjustment of a surrounding shell's thickness, a concept validated from continuum theory to atomistic scales and applicable to lightweight construction.
This paper proposes that turbulence is governed by an emergent oscillatory degree of freedom in the Reynolds stress, which unifies universal features like logarithmic velocity profiles and Kolmogorov constants through a geometric, gauge-covariant framework that offers a computationally efficient alternative to direct numerical simulation.
This paper employs asymptotic analysis to derive generalized Snell's laws for wave reflection and transmission at rapidly oscillating rough interfaces, characterizing how the correlation length of surface fluctuations relative to the beam width determines whether the fields manifest as random specular cones or deterministic cones accompanied by leading-order speckle patterns modeled as Gaussian random fields.
This paper introduces a unified framework based on a generalized vector wavefield called the -potential, which systematically derives all vacuum electromagnetic potentials, fields, and sources while preserving gauge freedom and charge conservation, and further provides a novel transformation method for generating new solutions from existing ones.
This paper investigates a Duffing resonator under bichromatic excitation, revealing how the competition between two drives in the slow-beating regime induces dynamical phase transitions between coexisting states, which are characterized by a cycle-averaged amplitude order parameter and mapped to provide a framework for controlling nonlinear systems across various platforms.
This paper demonstrates that a classical linear oscillator interacting with classical zero-point radiation achieves energy balance in both its ground state and resonant excited states, with the latter satisfying the quantization condition through the equilibrium between radiative energy loss and energy gain from the radiation field.
