physics.class-ph papers

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.

Formation of grain boundaries in ductile single crystals under plane-strain simple shear: a block-coordinate finite element method

This paper investigates the spontaneous formation of lamellar grain boundaries in ductile single crystals under plane-strain simple shear by employing a polyconvex continuum dislocation theory and a specialized block-coordinate finite element method to numerically resolve the microstructure arising from energy non-quasiconvexity and gradient regularization.

Numerical computation of high-order expansions of invariant manifolds of high-dimensional tori

This paper presents a highly parallel, efficient numerical algorithm with O(N log N) complexity that computes high-order Taylor-Fourier expansions of invariant manifolds for high-dimensional, reducible tori in stroboscopic Poincaré maps, utilizing a two-step quadratically convergent scheme and multiple shooting strategies to handle highly unstable cases.

Water wave scattering by a surface-mounted rectangular anisotropic elastic plate

This paper investigates the scattering of water waves by a surface-mounted rectangular anisotropic elastic plate with various edge conditions by combining a Rayleigh–Ritz method for dry modes and a boundary integral equation approach, revealing how symmetry constraints can forbid the excitation of specific resonant modes.

Generalizing Shell Theorem to Constant Curvature Spaces in All Dimensions and Topologies

This paper generalizes the Shell Theorem to constant curvature spaces of arbitrary dimensions and topologies by deriving the specific gravitational potentials that satisfy the spherical property using the Euler-Poisson-Darboux identity, thereby unifying known flat-space results and Gurzadyan's cosmological theorem.

Spurious quantum correlations

This paper demonstrates that certain quantum correlations, which appear non-classical within specific causal structures like Bell's, can be naturally explained classically in alternative causal structures without fine-tuning, while also identifying other quantum correlations that remain non-classical across all causal structures.

Painleve solitons of AKNS system and irrational algebraic solitons of NLS equations

This paper introduces a novel symmetry decomposition approach to derive "Painlevé solitons" for the AKNS system and NLS equations, significantly expanding the known solution landscape by generating new classes of irrational algebraic, rational algebraic, and parabolic cylindrical function solitons governed by Painlevé IV transcendent backgrounds.

Energy landscape and dissipation of sliding magnetic rotor arrays

This paper analytically investigates magnetic friction in sliding rotor arrays by mapping their energy landscape into distinct chambers, thereby identifying dynamical regimes, deriving friction scaling laws for various gaps, and explaining peak dissipation through energy jumps at chamber boundaries.

Planar Three-Body Problem: theoretical predictions and simulation results

This paper investigates the statistical properties of the non-hierarchical planar three-body problem by comparing theoretical predictions from Flux-based theory against one million numerical simulations, revealing that while some outcomes align well, others show unexpected discrepancies when contrasted with the unconstrained three-dimensional case.

The geometry of induced currents in two dimensional media

This paper establishes that two-dimensional superconductors are characterized by a Lorentzian contact manifold geometry, where the superconducting state is defined by the geodesic flow of induced currents and their non-vanishing helicity.

Path-Dependent Energy Lagrangian for Irreversible Thermomechanical Systems

This paper introduces a Path-Dependent Energy Lagrangian (PDEL) that unifies the mechanical balance equations and the entropy/heat equation for irreversible thermomechanical systems into a single action functional, utilizing a history integral of channel powers and a specific upper-limit variation rule to simultaneously generate dissipative forces and positive heat sources while ensuring thermodynamic consistency without auxiliary multipliers.
