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 investigates whether discrete bound state perturbations inside a Schwarzschild black hole can statistically account for its entropy, finding that while the angular degeneracy of these states scales with the horizon area, achieving full entropy saturation requires a significant energy fraction that necessitates ignoring backreaction effects.
This paper demonstrates that in a specific -dimensional quantum field theory at a biconical fixed point, the phase stiffness grows linearly with temperature, rendering vortex operators irrelevant and allowing a Berezinskii--Kosterlitz--Thouless superfluid phase to persist to arbitrarily high temperatures for sufficiently large .
This paper establishes a machine-verifiable, exact lower bound of approximately 0.9268 for the sharp constant in the Fisher-information convexity inequality along the two-dimensional heat flow by constructing a sum-of-squares certificate with eleven positive rational Gram matrices, thereby significantly improving upon the previously known universal value of 0.5 without requiring symmetry or log-concavity assumptions.
This paper constructs an observer-centric S-matrix for pure Yang-Mills theory in the expanding Poincaré patch of four-dimensional de Sitter space, defining asymptotic states along an eternal comoving observer's worldline to compute tree-level gluon scattering amplitudes that exhibit structures similar to cosmological correlators and satisfy de Sitter isometry Ward identities.
This paper resolves the discrepancy between the unique tracial state and semiclassical bulk correlations in de Sitter static patch holography by introducing heavy-clock states that reproduce -point functions, while extending the framework to include time-reversal symmetry via a generalized observer Hamiltonian and deriving this model from Einstein gravity coupled to Brown-Kuchař dust.
This paper computes the three-graviton amplitude in the Banks-Fischler-Shenker-Susskind matrix model for M-theory by relating it to a supersymmetric index computation in a compactified configuration, demonstrating agreement with expected super Poincaré invariant results even at finite .
This paper constructs a strongly rational, completely unitary chiral algebra of central charge eight whose representation category is equivalent to the Drinfeld center of the Haagerup fusion category, thereby providing a concrete realization of a Haagerup conformal field theory.
This paper challenges the conventional view that the primordial stochastic gravitational-wave background preserves early-universe information by demonstrating that high-occupation graviton states trigger rapid thermalization, which erases primordial details and produces a distinct high-frequency spectrum that is inaccessible to current low-frequency detectors but potentially observable with high-frequency technologies.
This paper proposes that the observed red spectral tilt in inflation can be explained without an inflaton field by attributing the necessary slow drift in the Hubble rate to the quantum break-time of de Sitter space, which generates a distinctive positive running of the spectral index and falsifiable predictions for the tensor spectral tilt.
This paper proposes that a nearly constant ratio of approximately 2.3 between the peak frequencies of gravitational waves from binary black hole mergers and those from evaporating black holes serves as a robust signature of new black hole physics, potentially allowing for the direct inference of specific properties like the Hayward model's hair parameter.
