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 investigates the water wave scattering by a surface-mounted rectangular anisotropic elastic plate with various edge conditions by combining a Rayleigh–Ritz method for dry mode expansion with a boundary integral equation solved via a constant panel method to analyze resonant responses and symmetry-forbidden mode excitations.
This paper presents a novel, parameter-free analytic model for predicting lateral spread in wire flat rolling, derived from governing equations and validated against stainless steel experiments, offering a rapid and robust tool for process design and finite element verification.
This paper derives the Planck law for black-body radiation using a classical variational principle that extremizes a generalized free energy functional incorporating Fisher information, relying solely on a minimal threshold assumption for photon emission rather than quantum mechanics.
This paper proposes a fast computational method for Hertzian contact theory that utilizes an incremental formula to accurately determine contact ellipticity with few iterations across a wide range of contact shapes, from near-perfect circles to highly elongated ellipses.
This study presents an analytical investigation of stress distributions in square elastic bodies under uniaxial and biaxial compressive loads by deriving closed-form Airy stress function solutions that satisfy the biharmonic equation and boundary conditions, showing strong agreement with experimental photoelastic data.
This paper develops reduced Field Dislocation Mechanics models for dislocation dynamics on a single slip plane that strictly enforce the space-time conservation of the Burgers vector, revealing fundamental structural and physical differences from the augmented Peierls model—particularly regarding dissipation localization and reference configuration dependence—and proposes a new, testable model to overcome these limitations.
