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 overcomes experimental limitations in applying the optical theorem to acoustics by developing a robust methodology that enables high-precision measurement of the extinction cross section for Helmholtz resonators, even in non-ideal anechoic environments with standing-wave resonances.
This paper clarifies the relationship between Einstein's second postulate and Maxwell's electromagnetic theory by presenting a simplified derivation of the Ignatowski approach to relativity and highlighting the unique position of the principle of relativity within Maxwellian physics.
This paper derives a universal acoustic sum rule analogous to the quantum Baldin sum rule, demonstrating that the integral of the extinction cross-section is fundamentally constrained by a scatterer's static effective mass and stiffness, thereby establishing a theoretical framework for optimizing the transmission loss bandwidth of passive metamaterials.
This paper proposes a thermo-geometric framework based on the Rayleigh quotient to describe relaxation dynamics as a competition between entropic stiffness and frictional dissipation, successfully characterizing the critical slowing down of a van der Waals gas near its critical temperature.
This paper proposes a non-integer-dimensional model for anisotropic solids using q-deformed derivatives inspired by Tsallis statistics to derive thermodynamic properties that accurately match experimental data while linking the deformation parameter to microscopic disorder and memory effects.
This study presents a computationally efficient semi-analytical Timoshenko beam model on a Winkler foundation to predict the transverse vibration and dynamic amplification of buried lifelines, revealing four distinct vibration regimes separated by transition frequencies and validated against finite element simulations.
This paper establishes a correspondence between axisymmetric razor-thin disks and linear mass distributions, identifying specific surface density profiles based on beta distributions that yield gravitational potentials expressible through single real quadratures or closed-form elementary functions.
This paper introduces a compact, efficient analytic operator-based approximation derived from full 2-body solutions that overcomes the limitations of traditional dipole models and computationally expensive full-field methods for describing interactions in magnetically soft many-body systems.
This paper derives the specific conditions on velocity and external force required for modified causal Lorentz-Abraham-Dirac equations of motion to conserve momentum and energy, clarifies the impact of mass renormalization on radiated energy, and presents solutions for a charge moving through a parallel-plate capacitor across various theoretical frameworks.
This paper refutes Zin and Pylak's objection to the causal modified Lorentz-Abraham-Dirac equation by demonstrating that velocity jumps across transition intervals near nonanalytic points in the external force do not produce delta functions in the radiated fields.
