hep-th papers | Gist.Science

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.

Perturbative and Non-Perturbative Contributions to Black Hole Thermodynamics with String Clouds and Dark Matter Backgrounds

This paper investigates how perturbative logarithmic and non-perturbative exponential quantum corrections modify the thermodynamic properties, stability, and phase structure of black holes immersed in a perfect fluid dark matter background with a cloud of strings in anti-de Sitter spacetime, revealing that while non-perturbative effects are significant only near the Planck scale, neither correction type yields a van der Waals-like critical point.

Entropy Quantization and Quasi-normal Modes of Dyonic Kerr-Sen Black Holes

This paper investigates the thermodynamics of dyonic Kerr-Sen black holes to demonstrate the universality of their entropy product and central charges, establish a Kerr/CFT correspondence that highlights differences from Kerr-Newman black holes, and derive analytical expressions for their quasi-normal mode spectra.

The limits of lattice inflation: a cautionary tale

This paper demonstrates that approximating the gravitational background as an exact FLRW spacetime in lattice inflation simulations prevents the freezing of superhorizon modes and significantly distorts inflationary observables, particularly during ultra-slow roll, prompting the authors to propose a validity criterion and implement it in CosmoLattice.

Domain walls and magnetic monopoles in Grand Unified Models

Motivated by Grand Unification, this study demonstrates that in an SU(3) gauge theory, a small non-vanishing bias parameter ( $\epsilon$ ) can suppress the over-abundance of magnetic monopoles by controlling the decay of domain walls, while simultaneously predicting a stochastic gravitational wave background and the potential formation of magnetically charged black holes.

On the Schubert calculus of the quantum K-theory for partial flag manifolds: a 3d A-model perspective

This paper investigates the correspondence between 3d gauged linear sigma models and the quantum K-theory of partial flag manifolds by computing correlation functions of Schubert line defects to derive K-theoretic Gromov–Witten invariants and Littlewood–Richardson coefficients, while also demonstrating how the small $\beta$ limit recovers known quantum cohomology ring relations.

Generalized Schwarzian Dynamics from a Bulk-First BF Perspective

This paper establishes a unified bulk-first framework deriving both ordinary and generalized Schwarzian dynamics from two-dimensional BF gravity via Drinfeld-Sokolov reductions, revealing how higher-rank sl(3,R) theories governed by Wilczynski invariants naturally link flat BF connections to projective geometry, Casimir charges, and boundary thermodynamics.

Constructing perfect spin-1 hydrodynamics from Boltzmann to Bose-Einstein statistics

This paper derives thermodynamic currents for a perfect fluid of massive spin-1 particles obeying Bose-Einstein statistics using the Wigner-function approach, demonstrating that the resulting spin-extended hydrodynamic framework provides a unified, causal, and stable description of relativistic spin hydrodynamics that is independent of both particle statistics and spin representation.

Quantum Corrections to Page Curve of Charged Near-AdS $_2$ Black Holes

This paper investigates how quantum corrections from Schwarzian and $U(1)$ soft modes in charged near-AdS $_2$ black holes modify the Page curve, revealing that the net shift in Page time results from a competition between the $U(1)$ mode's delaying effect and the Schwarzian mode's advancing effect.

Strong primordial inhomogeneities of axion-like field in Einstein-Gauss-Bonnet gravity

This paper proposes a model in Einstein-Gauss-Bonnet gravity where a complex scalar field with a Mexican hat potential undergoes a phase transition during inflation, generating strong small-scale primordial inhomogeneities and a gravitational wave background consistent with NANOGrav observations while avoiding large-scale isocurvature perturbations.

Testing the Nature of Rotating Black Hole Shadows Surrounded by a Thin Accretion Disk within Rastall Gravity

This paper employs ray-tracing simulations to demonstrate that in Rastall gravity, increasing the structure parameter $\gamma$ enlarges the shadow radius of a rotating black hole while simultaneously reducing its distortion, thereby offering a potential observational method to constrain the theory's parameters.
