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 chaotic inflation driven by potentials can be reconciled with recent ACT data and remain consistent with effective field theory constraints within the Palatini formulation of gravity by employing a specific non-minimal coupling to gravity and kinetic mixing, while also showing the model's embeddability in supergravity.
This paper investigates the geometric, dynamical, and thermodynamic properties of a static, spherically symmetric quantum Oppenheimer-Snyder black hole surrounded by quintessence and a cloud of strings, deriving its horizon structure, photon sphere, geodesic stability, quasinormal modes, and thermodynamic behavior to demonstrate that the model remains stable and free of negative-temperature phases despite the non-asymptotically flat geometry.
This paper presents new insights into the redistribution of geometric correlations on a Cauchy slice after the Page time, demonstrating that while mutual information between specific subsystems and vanishes at the scrambling time, mutual information between regions and becomes singular, and further provides a novel method to calculate the tripartite mutual information of these regions.
This paper investigates the Hilbert space structure of two-dimensional quantum gravity on closed spatial sections by analyzing gravitational wavefunctions through the Wheeler-DeWitt equation and path integrals, revealing topological corrections, large volume effects, and a connection to two-dimensional topological gravity up to genus six.
This paper extends the discrete classification of exponential scaling rates in quantum gravity to scalar field potentials, demonstrating that their asymptotic behavior is governed by brane tension taxonomy rules, which implies that potential gradients lie on a specific lattice and satisfy the Strong Asymptotic de Sitter Conjecture.
This paper investigates how external tidal fields in extreme-mass-ratio inspirals break spacetime axisymmetry to induce chaotic dynamics and tidal resonances, characterized by distinct plateaus in frequency ratios and phase-locked action-angle variables, which have significant implications for gravitational-wave inference in active galactic nuclei.
This paper develops a canonical ADM framework to analyze gravitational backreaction in de Sitter space, demonstrating that while the effect depends on gauge choices and cutoff schemes, it renormalizes the cosmological constant-Hubble relation without inducing secular instability in the inflationary background.
This paper investigates holographic fluctuation equations with apparent singularities approaching the boundary, demonstrating that their merger can generate either zeros or poles in spectral functions while preserving the validity of the holographic product formula.
This paper introduces a general technique for discovering new non-invertible symmetries in 2D chiral CFTs by constructing embeddings of parafermion algebras and identifying topological defects in various theories, including the Monster CFT, Leech lattice CFT, and heterotic string compactifications.
This paper investigates a multi-boundary many-body quantum teleportation protocol among three entangled qubit systems, demonstrating how a third system acts as a spatial filter that suppresses information transfer once scrambling reaches its entangled region, thereby offering a new method to resolve information spreading and distinguish genuine scrambling from noise.
