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 proposes a holographic correspondence where the observed cosmic acceleration, traditionally attributed to a cosmological constant, is instead explained as an entropic effect arising from the thermodynamic properties of the boundary's quantum degrees of freedom, a model known as GREA that predicts distinct deviations from the standard CDM model in the growth of large-scale structures testable by upcoming surveys.
This paper explains the absence of a finite-temperature spin glass transition in two dimensions by demonstrating that the system possesses an enhanced continuous symmetry leading to a line of renormalization group fixed points, while showing that in higher dimensions this symmetry can be spontaneously broken to yield a spin glass order parameter with continuous values.
This paper presents an independent re-analysis of DESI DR1 data using full-shape power spectrum and bispectrum measurements to derive robust, CMB-independent constraints on spatial curvature, dark energy dynamics, and neutrino masses, demonstrating significant improvements in cosmological parameter limits compared to standard BAO-only analyses.
This paper presents a model-independent framework that uses cosmic chronometer measurements of the Hubble parameter to directly reconstruct the background effective field theory functions of dark energy, enabling the testing of various cosmological models and the constraint of specific theories like quintessence without assuming a predefined scenario.
This paper establishes a precise holographic correspondence for ball-shaped entanglement entropy in excited states by explicitly calculating CFT corrections via modular-flowed Witten diagrams and demonstrating their exact match with the quantum extremal surface formula, including backreaction-induced shape deformations of the entanglement wedge.
This paper utilizes holographic models of near-extremal AdS black holes to demonstrate that 2D quantum critical theories with strong translational symmetry breaking and zero average chemical potential exhibit enhanced conductivity, bad-metal electrical transport with non-Drude thermal behavior, and approximately linear-in-field magnetoresistance.
This paper constructs and analyzes singly and doubly spinning non-supersymmetric F1-P black ring solutions in five-dimensional supergravity, demonstrating that the doubly spinning configuration admits an extremal limit where the entropy satisfies the relation .
Through extensive time-domain numerical simulations of a Schwarzschild black hole in a cubic-in-curvature effective-field-theory extension of general relativity, this paper demonstrates that while the loss of isospectrality between polar and axial quasinormal modes complicates the identification of individual fundamental modes in gravitational waveforms, it can still provide evidence for non-general-relativistic physics.
This paper demonstrates that regularizing (2+1)-dimensional Minkowski spacetime with a finite-resolution Gaussian probe induces a curved geometry featuring a topological defect with universal negative energy, revealing that finite spatial resolution fundamentally shapes spacetime structure rather than merely smoothing singularities.
This paper establishes a general framework for constructing -site chiral integrable matrix product states in the ABJM spin chain using reflection equations and fusion, while deriving exact overlap formulas for four-site states and investigating their chiral integrable subspaces numerically.
