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 proposes a momentum-space dual of Fock--Lorentz transformations to derive a deformed relativistic mass shell with a time-dependent apparent mass, which is then used to formulate and solve Klein--Gordon and Dirac oscillators, revealing that their energy spectra collapse toward zero as the apparent mass vanishes in the limit of infinite time.
This paper investigates a quadratic gravity model that introduces an term to the Friedmann equation, demonstrating that its weakened effective gravitational coupling can reproduce background cosmological observations while naturally alleviating the tension by suppressing structure growth.
This paper critiques the traditional Boltzmann definition of entropy as the logarithm of quantum states, proposing instead that entropy arises from subquantum processes and is mathematically expressed as the ratio of the logarithm of a macroscopic system's maximum state realizations to the frequency of its quantum state occurrences over a given observation period.
This paper demonstrates that the Gödel universe, an exact solution to Einstein's field equations, acts as a gravitational analogue to a superconductor in its Meissner state, thereby filling a gap in the use of geometric and topological tools to model material media.
This paper argues that the inverted harmonic oscillator, as the universal Hamiltonian of unstable equilibrium, governs the spin-2 sector of a unique unitary and renormalizable quantum gravity theory, thereby correcting historical approaches to quantum gravity and predicting a non-singular universe with Starobinsky inflation.
This paper presents a new theory for massive, eight-dimensional covariant fields with a unique spin of 3/2 by constructing the framework from a reducible representation rather than the standard irreducible one, thereby enabling the natural separation of the spin-1/2 sector to isolate the genuine spin-3/2 field and derive its complete formalism including equations, Lagrangian, and mode spinors.
This paper generalizes Tweed's Born I formalism for electron-impact double ionization of two-electron systems (, , and ) to non-extensive Tsallis -statistical plasma environments, deriving modified cross sections and rate coefficients that reveal unique screening effects, diffraction-like oscillations, and a novel subextensive critical temperature threshold below which ionization is forbidden.
This paper proposes a unified cosmological scenario within holographic gravity that successfully describes both early inflation and late-time cosmic acceleration, demonstrating consistency with Planck 2018 inflationary constraints and observational data from Cosmic Chronometers and Baryon Acoustic Oscillations while remaining comparable to the standard CDM model.
This paper demonstrates that critical Hawkes point processes with heavy-tailed fertility distributions can achieve stationarity in law despite having infinite mean activity, provided that the memory and fertility tail exponents satisfy specific conditions ensuring the local finiteness of the underlying infinite-past Poisson-cluster construction.
This paper extends canonical quantization in quantum field theories by utilizing flat bundles on infinite-dimensional functional manifolds to reformulate the S-matrix as a T-exponent, thereby offering a first-principles framework for bound states and demonstrating how spacetime notions emerge as spectral sets of functional differential operators.
