General Physics explores the fundamental laws that govern everything from the tiniest subatomic particles to the vastness of the cosmos. This field serves as the bedrock for understanding how the universe operates, covering mechanics, thermodynamics, and electromagnetism without getting bogged down in overly specialized sub-disciplines. It is where the big questions about matter, energy, and force come together to explain the physical world around us.
At Gist.Science, we process every new preprint in this General Physics category as it arrives from arXiv, ensuring you never miss a breakthrough. For each paper, we provide both a detailed technical summary for experts and a plain-language explanation that makes complex ideas accessible to everyone. Below are the latest papers in General Physics, freshly summarized and ready for you to explore.
This paper derives analytical expressions for the time evolution of the expectation values and second moments of observables that are conserved under Hamiltonian dynamics but become non-conserved due to Markovian environmental coupling, illustrating how collapse operators break conservation laws and generate fluctuations through various quantum models.
This paper derives modified Friedmann equations based on Rényi entropy to constrain the Rényi parameter using Big-Bang Nucleosynthesis data, revealing that while the parameter ranges derived from Helium-4 and Deuterium overlap, their discrepancy with the Lithium-7 range suggests a potential mechanism for alleviating the long-standing Lithium problem in early-universe cosmology.
This paper argues that despite the Standard Model's experimental success, its algebraic foundations are fundamentally flawed because chiral symmetry is mathematically inconsistent with neutrinos possessing finite mass as fermions.
This paper proposes a Unified Entropic Dynamics (UED) framework that derives classical, quantum, relativistic, and gravitational wave equations from a single information-geometric principle of entropy maximization, revealing these diverse physical laws as complementary expressions of probabilistic inference on a manifold.
This paper develops a systematic formulation of statistical mechanics on Euclidean Snyder space to derive temperature-dependent thermodynamic corrections that suppress energy and entropy, which are then applied to early-Universe cosmology to establish stringent bounds on the Snyder deformation and Generalized Uncertainty Principle parameters using Big Bang Nucleosynthesis constraints.
This paper investigates the evolution of cosmic structures in a viable power-law gravity model, demonstrating that the curvature correction enhances matter perturbation growth while satisfying stability criteria and offering distinct observational signatures for future large-scale structure surveys.
This paper introduces a unified framework based on -modified Einstein field equations that defines degenerate wormholes by a vanishing metric determinant, demonstrating that both Einstein-Rosen bridges and Klinkhamer defects are exact vacuum solutions capable of traversability without exotic matter, thereby distinguishing them from standard non-degenerate wormholes that require NEC violation.
This paper introduces a compact, observer-explicit geometric diagnostic framework that distinguishes between distinct physical mechanisms driving departures from the FLRW idealization in cosmological solutions of Einstein's field equations, successfully categorizing six benchmark spacetimes while retaining Buchert's kinematical backreaction as a derived quantity.
This paper demonstrates that gravitationally induced photon production in an expanding universe leads to a consistent extended temperature law and preserves the blackbody spectrum across three independent theoretical frameworks, offering a potential resolution to the Hubble tension and a new test for the standard cosmological model.
This paper investigates the effective four-dimensional cosmology of unimodular gravity in dimensions by employing dynamical systems analysis to demonstrate that the resulting FLRW equations exhibit a phase-space structure qualitatively distinct from general relativity, featuring continuous equilibrium families in the vacuum sector and isolated critical points with globally organized compactified flow in the matter sector.
