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 introduces the CET Omega framework, which predicts a doubly logarithmic correction to early-universe radiation energy density, and uses Planck 2018 and BBN data to constrain the correction parameter to , finding it consistent with zero while establishing current observational bounds and forecasting future sensitivity with CMB-S4.
This paper uses Markov Chain Monte Carlo analysis of cosmic chronometer, Pantheon+SH0ES, and DESI DR2 datasets to constrain two decaying vacuum cosmological models, finding they favor a Hubble constant of approximately 72.5–73.0 km/s/Mpc and a mild deviation from the standard CDM framework while successfully describing the universe's transition from deceleration to acceleration.
This paper derives the equations of motion for the mass centers of a system of weakly gravitating bodies within the second version of a scalar theory of gravity that interprets gravity as a pressure force, utilizing a post-Newtonian approximation framework to transition from local field equations to global body dynamics.
This paper applies the Fluctuation Dissipation Theorem to Aharonov-Bohm electrodynamics, demonstrating that while the total thermal energy spectrum matches Maxwell's theory due to a compensating negative scalar field contribution, the electric field energy doubles, and that for conductors with local charge non-conservation, the model predicts a violet noise component added to the classical Johnson-Nyquist white noise.
SWEEP is a unified, extensible, and differentiable wave equation solver framework that supports diverse seismic propagation models and plug-and-play components to facilitate advanced gradient-based inversion tasks like full-waveform inversion and least-squares reverse time migration.
This paper proposes a local gauge-covariant framework for classical dynamics where physical laws emerge from the asynchronous relaxation of local incompatibilities between state variables and transport geometry, recovering familiar continuum equations without assuming predefined evolution laws or an external time parameter.
This paper utilizes high-performance CUDA simulations combined with the Hamilton–Jacobi formalism to investigate the shadows and energy emission rates of rotating charged Euler–Heisenberg black holes with global monopoles, revealing that while the global monopole, electric charge, and rotation parameters significantly influence these properties, the Euler–Heisenberg nonlinear parameter has a negligible effect, thereby enabling the establishment of strict bounds on the former parameters to reconcile with Event Horizon Telescope observations.
This paper resolves the Rayleigh–Riabouchinsky paradox by recasting thermodynamics as the complete-similarity limit of statistical mechanics, where Boltzmann's constant introduces a system-size dimensionless group that becomes irrelevant in the macroscopic limit, thereby unifying dimensional analysis with the suppression of thermodynamic fluctuations.
This paper proposes that the CPT gravity theory and its associated lattice Universe model naturally explain the unexplained ANITA anomalous upward-going radio events and AMS-02 antihelium candidates without requiring dark energy or ad hoc hypotheses.
This paper presents a mathematical formalism for a -dimensional manifold featuring -correlators of -type objects with cross-correlations and contaminants, constructed using concepts from mathematical physics, field theory, topology, algebra, and statistics, and demonstrates its applicability across cosmological scales from astronomical to quantum levels.
