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 demonstrates that global symmetries are violated in Hawking radiation by modeling black holes as non-isometric codes, which cause non-zero overlaps between states of different charges and yield Renyi entropies consistent with the quantum extremal surface formula.
This paper corrects previous calculations of the primordial bispectrum in single-field inflation by computing second-order slow-roll corrections, revealing that these next-to-leading order terms can be as significant as the leading order results in models like hilltop inflation.
This paper introduces a generalized cluster ladder model that utilizes weak Hopf symmetry to construct a lattice realization of (1+1)D symmetry topological field theory, providing an exact solution via weak Hopf tensor network states for arbitrary fusion category symmetries.
This paper proposes that small black holes could catalyze the decay of a false Higgs vacuum, creating expanding true vacuum bubbles whose friction-induced thermal production of Higgs particles generates detectable high-energy photon and neutrino bursts that could serve as early warning signals before the bubble wall reaches Earth.
This paper presents the first natural realization of inverse bubbles within a supersymmetry-breaking sector, demonstrating through numerical analysis that inverse hydrodynamics—where fluid is aspirated by the bubble wall—can occur in standard cooling cosmology and establishing a generic criterion based on the generalized pseudo-trace to predict such fluid behaviors.
This paper proposes a manifestly duality-invariant, Lorentz-invariant, and local action for quantum electrodynamics with magnetic monopoles, derived from Sen's formalism using field strengths as dynamical variables, which resolves prior ambiguities and confirms consistent renormalization and charge quantization at both tree and loop levels without external assumptions.
This paper presents novel analytical solutions to the Klein-Gordon equation for scalar particles in a black string spacetime immersed in anisotropic quintessence and a string cloud, utilizing Heun and Bessel equations to derive radial solutions across all relevant quintessence state parameters and identify constraints leading to spectral restrictions and dark phases.
This paper demonstrates that introducing internal spin to billiard systems monotonically suppresses chaos by reducing the Lyapunov exponent and creating islands of regularity through a conserved quantity, yet fails to eliminate chaos entirely in non-integrable geometries like the Bunimovich stadium and Sinai billiard.
This paper analytically calculates the scalar self-force, energy, and angular momentum fluxes for a particle in a slightly eccentric orbit around a Schwarzschild black hole up to 6PN order and fourth order in eccentricity, demonstrating perfect agreement with scalar-tensor theory results when the asymptotic scalar field is fixed to unity.
This paper constructs a basis for the nonperturbative Hilbert space of quantum gravity with a single asymptotic boundary and demonstrates that the Hilbert space for a system with two disconnected boundaries factorizes into the tensor product of two such single-boundary Hilbert spaces.
