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 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 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.
Motivated by a recent comment, this paper provides an explicit and elementary derivation showing that a Dirac string, modeled as a semi-infinite solenoid, experiences a divergent self-force proportional to the square of its magnetic flux divided by the square of its radius as the radius approaches zero.
This paper presents a differentiable computational framework for the continuous reprogramming of Totimorphic lattices' effective mechanical and optical properties through geometric optimization, enabling autonomous self-configuration and self-repair for deep space applications such as adaptive telescope mirrors.
This paper proposes an angular-momentum preserving dissipative model for the N-body problem that reduces to homographic equations for central configurations, analyzes the resulting two-body dynamics via Poincaré compactification, and demonstrates that the dissipation does not affect periapsis precession.
This paper demonstrates that the Mpemba effect, where a system initially farther from equilibrium relaxes faster than a closer one, can occur within the linear-response regime of many-body systems through spectral separation in reciprocal systems and non-normal relaxation dynamics in non-reciprocal systems.
This paper demonstrates that within a distributional framework, the Principle of Virtual Work is necessary to characterize equilibrium in higher-gradient continua where balance laws alone are insufficient, and it clarifies that Noll's theorem regarding surface contact forces relies on assumptions that fail for such materials, thereby validating the existence of curvature-dependent contact interactions.
This paper investigates band modulations and topological transitions in a one-dimensional periodic bead-on-string chain by combining exact transfer-matrix analysis, numerical simulations, and tabletop experiments to demonstrate that localized midgap states are topological solitons governed by the Su-Schrieffer-Heeger model and Dirac theory.
