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 provides a theoretical and experimental analysis of Fraunhofer diffraction patterns produced by aperiodic slit arrays, establishing general conditions for observing interference maxima in structures that exhibit periodic features across multiple distance scales.
This paper proposes a framework for particle mechanics derived from the principle of local energy conservation rather than Newton's laws, demonstrating that Newtonian and relativistic mechanics emerge as unique solutions when symmetry principles like rotational equivariance and relativity are applied to this energy-based structure.
This paper demonstrates that by introducing three minimal inductive biases—spatial smoothness, stability, and temporal locality—generic Transformers can evolve from mere curve-fitters into agents capable of discovering fundamental physical laws like Newtonian forces, thereby bridging the gap between high predictive accuracy and true causal understanding.
This paper resolves the tension between d'Alembert-Lagrange and integral variational approaches in nonholonomic mechanics by demonstrating that the commutation of variation and differentiation is generally incompatible with Chetaev's principle unless specific geometric conditions are met, while revealing that dynamic consistency can emerge as a collective phenomenon where interactions between multiple non-integrable constraints cancel out deviations from holonomy.
This paper reveals that in the infinite-permeability limit, the entire external magnetic response of a body is determined solely by its outer surface geometry, independent of internal structure, a geometric invariance that offers a theoretical foundation for lightweight magnetic device design and extends across various Laplace-governed physical phenomena.
This paper proposes a new perspective on the acousto-electric effect by deriving a wave equation for the acoustic field, analogous to Stokes' 1845 viscous wave equation, where phonon-electron interaction acts as a loss or gain term to establish connections with inertial motion superradiance and the Zel'dovich effect.
This paper presents a Hamiltonian framework for regularizing and linearizing central-force dynamics by introducing a new canonical extension of projective decomposition, which yields closed-form solutions for inverse-square and inverse-cubic forces and is validated numerically for the two-body problem with J2 perturbations.
This paper presents the first experimental observation of non-Hermitian dislocation bound states and dislocation-induced skin effects in two-dimensional acoustic Chern lattices, demonstrating how precision-controlled gain and loss enable the probing of non-Hermitian topology through lattice defects.
This paper generalizes the Shell Theorem to constant curvature spaces of arbitrary dimensions and topologies by deriving gravitational potentials with spherical properties using the Euler-Poisson-Darboux identity, thereby unifying known flat-space results and Gurzadyan's cosmological theorem.
This paper presents a coordinate-free introduction to exterior forms for physics students, emphasizing their physical significance by deriving classical equations only after establishing the formalism without relying on specific coordinate frames.
