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.

Accelerating universes generated by off-diagonal deformations and geometric flows of black holes in Einstein gravity vs f(R)f(R) gravity

This paper argues that accelerating universes and effective dark energy can be derived within standard Einstein gravity and geometric flow theories by constructing new classes of off-diagonal solutions that smoothly transform black hole configurations into cosmological geometries, thereby offering an alternative to the proliferation of modified gravity theories.

Three-Dimensional Modified Dirac Oscillator in Standard and Generalized Doubly Special Relativity

This paper presents an exactly solvable three-dimensional model of the Dirac oscillator within Standard and Generalized Doubly Special Relativity frameworks, demonstrating how Planck-scale deformations modify the energy spectrum and introduce branch-dependent shifts for particle and antiparticle states while preserving the system's fundamental oscillator-spinor structure.

Quantum geometry from commutators: a Heisenberg-picture framework and a toy application to early structure

This paper proposes a Heisenberg-picture kinematical framework where the spacetime metric emerges as a quantum operator defined by non-commuting translation generators, utilizing a gravitational conjugation symmetry to treat time as an observable and demonstrating how metric fluctuations could rescale primordial amplitudes to influence early structure formation.

Quantum-Kinetic Dark Energy (QKDE): An effective dark energy framework with a covariantly completed time-dependent scalar kinetic normalization

This paper introduces Quantum-Kinetic Dark Energy (QKDE), a minimal effective framework featuring a covariantly completed, time-dependent scalar kinetic normalization that preserves standard Einstein-Hilbert gravity and luminal tensor propagation while generating distinct observational signatures solely through the expansion history and induced growth of structure.
