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 in large-dimensional discretely self-similar collapse, anomaly-induced backreaction from the Polyakov model prevents a generic smooth, exactly self-similar completion of the classical center by introducing a critical dilaton surface that leads to singularities or a narrow, high-curvature throat.
This thesis investigates foundational puzzles in quantum theory by extending Wigner's friend scenarios to derive new no-go results on nonclassicality and free choice, and by unifying these arguments with black hole information paradoxes to strengthen cloning and firewall contradictions while analyzing detector responses near superposed black holes.
This paper formulates a nonlocal spin-1/2 field theory in curved spacetime using nonpolynomial entire functions of the Dirac operator, demonstrating that its dynamics map to a local Dirac equation with Lambert--dependent effective masses while preserving the Euclidean analyticity of the Bunch--Davies vacuum and recovering the local theory in the infinite cutoff limit.
This paper calculates the momentum flux of small-amplitude oscillons in -dimensional scalar field theory, demonstrating that the integrated flux over a period is extremely small, scaling as or depending on the parity of the truncation order .
Inspired by cosmological collider physics, this paper introduces Quasinormal-Mode Collider Spectroscopy (QCS), a framework that analyzes nonlinear black hole ringdown by establishing factorization rules and reconstruction methods to connect lower-order radiation with higher-order observables, thereby revealing the interaction structure and intermediate states of merger remnants.
This paper constructs operator product expansions and derives the full celestial soft symmetry algebras in both holomorphic and antiholomorphic sectors, demonstrating their extension of the BMS algebra and identifying key generators like the stress-energy tensor and supertranslation currents via shadow transforms.
This paper explores two physical consequences of the topological classification of two-dimensional free lattice Fermi seas on flat orbifolds: the emergence of anisotropic Friedel oscillations that reveal lattice symmetries in the spatial density, and a geometric correspondence linking momentum-space packing to electrical conductivity via an isoperimetric parameter.
This paper demonstrates that extremal near-horizon geometries for smooth stationary black hole families can be systematically recovered from non-extremal expansions by applying specific near-extremal scalings to surface gravity, radial coordinates, and Killing time, a method that successfully reproduces the known throats of Reissner-Nordström, Kerr, Kerr-Newman, and charged rotating BTZ black holes.
This paper demonstrates that the critical zero mode of holographic superconductors, despite vanishing in the exterior, governs the nonuniform interior geometry of charged black holes by fixing the Einstein-Rosen collapse width and Josephson phase, which in turn dictate oscillatory Kasner dynamics and zero-accumulation laws, while low-temperature behavior is instead determined by the infrared completion of the zero-temperature geometry.
This paper establishes a speed limit for information propagation in Krylov subspaces by deriving causality constraints on Lanczos coefficients that lead to super-ballistic lightcones, extending these bounds to Q-complexities, and mapping the dynamics to spin chains to enable the application of standard condensed matter methods.
