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.

Below are the latest papers in General Physics, freshly summarized and ready for you to explore.
This paper employs a covariant formalism to analyze how background gravitational fields influence light propagation in linear magnetoelectric media and magnetized plasmas, providing estimates for detecting these effects through precise refractive index measurements.
This paper proposes a finite algebraic formulation of quantum field theory for elementary particles, utilizing the spectral properties of orthogonal polynomials to eliminate divergences in Feynman diagram loop integrals and thereby remove the need for renormalization.
This paper demonstrates that combining a convolutional neural network autoencoder with manifold-based normalization significantly improves the detection of resolvable gravitational-wave sources within LISA's confusion-limited background, achieving a 35% performance boost over reconstruction error alone by leveraging latent-space geometric structure.
This paper argues that the apparent discrepancies between early-universe galaxy properties and standard CDM predictions are resolved by the CCC+TL cosmology, which posits covarying coupling constants and a tired light effect to explain observed redshifts, thereby reconciling galaxy size, mass, and density evolution with observational data without requiring unrealistic formation rates.
This paper proposes a covariant Gross-Pitaevskii-like equation derived from a specific Lagrangian to study interacting relativistic fermions, demonstrating its applicability in explaining phenomena such as the Migdal step in Fermi liquids, superconductivity spectra, and quark confinement in (3+1) spacetime.
This paper demonstrates that applying the same entire-function regulator used to ensure ultraviolet finiteness in nonlocal quantum field theories to the energy-momentum tensor of a point mass resolves the curvature singularity by replacing it with a regular de Sitter core in the resulting static, spherically symmetric spacetime solution.
This paper demonstrates that the coefficient in the Bekenstein--Hawking black hole entropy formula arises purely from the causal geometry of null boundaries in four-dimensional spacetime, derived via symplectic structures and causal splitting without invoking gravitational field equations.
This paper investigates dynamical dark energy models within an anisotropic Bianchi Type-V universe using a covariant thermodynamics approach and confronts them with the latest DESI DR2, SNIa, and RSD datasets, finding that the combined anisotropy and dynamical dark energy framework effectively accommodates late-time observations and mitigates the and tensions, despite Bayesian criteria still favoring the standard CDM model.
This paper introduces a phenomenological model with a constant parameter describing an early-time interaction between a scalar field and radiation that modifies photon scaling, and preliminary constraints using Pantheon+SH0ES supernova and BAO data suggest this extension is favored over the standard model by the AIC criterion.
This paper proposes that the observed identity of a Damour-Solodukhin wormhole as either a black hole or a wormhole depends on the observer's location, utilizing Tangherlini's concept of gravitational indeterminacy to show that Fresnel reflection and transmission coefficients for probing photons are determined solely by the wormhole's free parameter rather than its mass.
