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.

Tuning A Rotating Black Hole Spectrum with Dark Matter Halo: Quasibound States, Scalar Cloud, Black Hole Bomb and Superradiant Scattering

This paper investigates how a rotating black hole embedded in a Dehnen dark matter halo exhibits modified quasibound state spectra and superradiant scattering, demonstrating that the halo's density and profile parameters act as an environmental tuner that systematically shifts binding energies, alters instability thresholds, and narrows the superradiant amplification window.

Pair creation amplitudes for a real scalar field coupled to a time-dependent surface in d+1 dimensions

This paper investigates the pair creation of a real scalar field induced by a time-dependent deforming surface with Dirichlet-like boundary conditions in d+1d+1 dimensions, deriving the angular dependence of the emission rate up to fourth-order deformations and clarifying the relationship between exclusive probabilities and the imaginary part of the effective action when two-pair channels open.

Spacetime from Operator Algebras

This paper proposes a framework where spacetime geometry and the full non-linear Einstein equations emerge from the algebra of quantized matter fields in the vanishing Newton's constant limit, while also demonstrating how non-perturbative corrections and ensemble averaging of these operator algebras can model the discrete spectrum of holographic theories and reproduce black hole entropy with logarithmic corrections.

A Friendly Phantom: Late-time AdS-to-dS transition and cosmological tensions

This paper introduces Ph-Λs\Lambda_{\rm s}CDM, a General Relativity model utilizing a phantom scalar with a wrong-sign kinetic term to drive a smooth late-time transition from anti-de Sitter to de Sitter space, thereby offering a controlled mechanism to resolve cosmological tensions without resulting in a Big Rip.

Supersymmetry of the static Reissner-Nordström black hole in Bertotti-Robinson (AdS2×S2\mathrm{AdS}_2 \times \mathbb{S}^2)

This paper investigates the supersymmetry of charged and accelerating black holes within an N=2N=2, D=4D=4 supergravity framework on a Bertotti-Robinson background by deriving Killing spinors, demonstrating BPS saturation to determine the black hole's mass and thermodynamics, and generalizing the extremal solution to include a cosmological constant.
