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 spacetime curvature within a five-dimensional dilaton-gravity system can classically stabilize black strings extending from a flat brane to a timelike boundary, even in cases where the strings possess infinite horizon area.
This paper presents a hybrid method combining machine learning, analytic ansätze, and symbolic regression to construct approximate closed-form expressions for Ricci-flat Kähler metrics on Calabi-Yau threefolds that explicitly depend on Kähler moduli, successfully demonstrating percent-level accuracy for two specific examples with .
This paper investigates entanglement harvesting between two qubits coupled to a massless scalar field in the Minkowski vacuum, where one qubit is inertial and the other undergoes uniform circular motion, analyzing how the radius and angular velocity of the rotating qubit influence the generation of entanglement and mutual information.
This paper argues that time-reversal in de Sitter space is a spontaneously broken gauge symmetry of the bulk, evidenced by a specific holonomy that flips the direction of time along closed curves, thereby reconciling conflicting views from Harlow and Witten.
This paper computes the vacuum expectation value of the stress-energy tensor for a scalar field on a product spacetime consisting of an FLRW background and a time-dependent compact dimension by modifying the adiabatic regularization prescription to derive analytic expressions that recover known Casimir and FLRW results in specific limits.
This paper establishes a fully relativistic framework for slowly rotating two-fluid neutron stars that reveals intrinsic collective rotational eigenmodes and demonstrates that the preservation or breakdown of rotational-tidal universality depends on dark-sector microphysics rather than simply the presence of an additional gravitationally coupled component.
This paper investigates the thermodynamic geometry and phase transitions of Anti-de Sitter black holes in ModMax, nonlinear electrodynamics, and Euler-Heisenberg theories under standard, Rényi, and Kaniadakis entropy frameworks, demonstrating that singularities in the geometrothermodynamic curvature consistently identify critical points that are preserved in their holographic dual conformal field theories.
This paper re-evaluates the viability of Minimal Warm Inflation driven by an axion-like inflaton coupled to non-Abelian gauge bosons, concluding that while the clockwork mechanism fails to generate the necessary hierarchy between decay constants, effective descriptions satisfying partial-wave unitarity bounds remain consistent with observational constraints.
Using a soft-wall holographic QCD model calibrated to reproduce the physical pion mass and pseudocritical temperature, this study demonstrates that while chiral symmetry restoration is clearly signaled by the degeneracy of chiral partner meson screening masses near , the restoration of axial symmetry occurs at a distinctly higher temperature ( GeV), highlighting a qualitative limitation of the model in describing the axial anomaly compared to Lattice QCD.
This paper investigates the algebraic structure of two-time physics by demonstrating that its extended phase space corresponds to a reduced Freudenthal triple system over a Lorentzian spin factor, where gauge fixing restricts the system to specific nilpotent orbits, a framework illustrated through both relativistic and non-relativistic physical models.
