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 proposes a Non-Propulsive Payload Deployment (NPD) architecture for on-orbit servicing of mega-constellations, which significantly reduces fuel consumption by ejecting micro-payloads to autonomously rendezvous with targets, while introducing a phase-based algorithm and analytical formulas that enable efficient, low-error scheduling and planning for large-scale constellations like Starlink Gen2.
This study reveals that in thick magnetic films, the reflection of chirally protected surface spin waves is mediated by the excitation of localized bulk modes, a mechanism that defines the limits of backscattering immunity in nonreciprocal magnetic media.
This paper demonstrates that the relativistic energy-momentum relation emerges as an effective ensemble-averaged structure from a multiplicative Hamiltonian under maximum entropy inference, where scale-invariant constraints derived from Fisher-Rao geometry naturally yield the relativistic dispersion relation without initially imposing Lorentz symmetry.
This paper reports the discovery of "exceptional deficiency," a new non-Hermitian singularity involving the complete coalescence of two arbitrarily large eigenspaces and their spectral continua, which induces anomalous skin effects and synergistic dynamics that have been experimentally verified in active mechanical lattices.
This contribution presents an analytical investigation of the influence of magnetic fields on ion transport in concentrated solid solutions, derives general multicomponent transport equations, and demonstrates that a specific model for binary conductors accurately describes the experimental magnetoresistance data for PbCdF under the assumption of nearly degenerate multicomponent transport.
This paper presents a complete analytical solution for the stress field inside a homogeneous, linearly elastic sphere subjected to a concentrated normal surface load, derived via elastodynamic equations and spherical harmonic expansions, with results generalized to arbitrary loading positions through rotational transformations and superposition.
This paper proves that the Lorentz-FitzGerald contraction is the unique deformation required for a moving resonant cavity to preserve its spherical-harmonic eigenstructure, thereby deriving both length contraction and time dilation as necessary consequences of phase closure in a mechanical wave medium without additional assumptions.
This paper demonstrates that classical physics emerges from quantum mechanics through finite-resolution measurements, showing that when the measurement resolution exceeds Planck's constant, quantum statistics admit a positive classical probability density evolving via a smoothed Hamiltonian flow that reproduces classical trajectories.
This paper argues that despite the widespread textbook acceptance of infinite electromagnetic self-energy for point charges, a re-examination reveals that electrons must be point particles with zero electromagnetic self-energy.
This paper theoretically and numerically demonstrates that beating two co-propagating laser pulses on a smooth cylindrical plasma-vacuum interface can resonantly excite high-amplitude surface plasmon wakefields, offering a pathway to portable laser-driven plasma accelerators using state-of-the-art gigawatt fiber lasers.
