Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper establishes a no-go theorem demonstrating that the most general bumblebee vector-tensor theory cannot simultaneously support a homogeneous and isotropic cosmological background, avoid extra propagating degrees of freedom, and maintain healthy linear perturbations, as enforcing the correct number of modes inevitably leads to an infinitely strongly coupled scalar sector.
This paper extends the holographic Complexity-equal-Volume framework to timelike subregions in AdS and black brane geometries, demonstrating that the resulting complexity remains purely real with universal UV divergences, thereby distinguishing its geometric nature from the complex-valued pseudo-entropy.
This paper establishes the gauge-invariant status of entire-function regulators in nonlocal quantum field theory by demonstrating, within the background-field formalism, that these regulators act as multiplicative form factors in momentum space to provide exponential ultraviolet damping without introducing new singularities.
This paper demonstrates that atomic clock measurements, combined with Lunar Laser Ranging and photon trajectory data, provide the strongest constraints to date on scalar tensor dark energy, effectively ruling out most locally coupled models and forcing viable theories toward near-Lambda CDM behavior or fully decoupled fields.
This paper unifies three distinct black hole thermodynamic classification schemes—geometric, topological, and complex—by demonstrating that they are precisely mapped onto one another through the critical point structure of the temperature curve, thereby simplifying the analysis of thermal stability and phase transitions.
This paper proposes two novel nonequilibrium dynamical crossover lines in the supercritical region, defined by the peak rate of inhomogeneous structure formation and the turning point of topological defect invasion velocity, respectively, to characterize supercritical subphases by integrating both thermodynamic and dynamical information.
Motivated by the holographic swampland program, this paper proves a Weak Gravity Conjecture-inspired bound on the subleading coefficient of the large-charge scaling dimension in 3d CFTs with spontaneous symmetry breaking, while demonstrating that the leading coefficient admits no universal bound and providing explicit computations for various theories.
This paper serves as a methodological companion to a study on minimal surfaces in hyperbolic space, detailing how encoding geometric constraints directly into the neural network architecture and optimizing PDE residual evaluation through second-order jets and graph compilation can reduce training costs by a factor of forty to fifty, thereby enabling efficient Physics-Informed Neural Network applications in geometric analysis.
This paper derives a microscopic electromagnetic membrane paradigm for black holes from matrix quantum mechanics, demonstrating how tachyonic condensation of bifundamental modes couples the horizon to the exterior field to yield Ohmic conductivity that saturates the maximal absorption bound imposed by unitarity.
This paper investigates the excitation region of Kerr black hole quasinormal modes by combining analytical Stokes geometry analysis with numerical convergence tests to demonstrate that the effective excitation radius depends on the overtone number, differing from the light ring and approaching the outer horizon in the extremal limit.
