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 advances the quantum simulation of massive Thirring and Gross–Neveu models with arbitrary fermion flavors by analyzing their gate complexity, classifying their dynamical Lie algebras, and successfully preparing their ground states using an adaptive-variational quantum imaginary time algorithm.
This paper develops a unified Schwinger-Keldysh field theory framework to characterize operator growth and entanglement dynamics in non-interacting disordered systems, demonstrating how subsystem operator Rényi entropy serves as a state-independent probe that directly links transport behaviors—ranging from ballistic and anomalous diffusion to localization—to the generation of entanglement.
This paper derives a novel action for two decoupled self-dual gauge fields from a new superstring field theory, which features non-standard couplings to three metrics, exhibits two spin-two gauge invariances with diffeomorphisms arising from their diagonal subgroup, and reduces to Sen's theory in a specific limit.
This paper derives the exact analytic energy spectra and Planck-suppressed shifts for a three-dimensional Klein--Gordon oscillator under standard Amelino-Camelia and Magueijo-Smolin Doubly Special Relativity frameworks, as well as a generalized first-order expansion, demonstrating how these deformations alter the quantization condition while preserving the system's rotational symmetry and functional eigenstructure.
This paper proposes a renormalizable supersymmetric B-L Higgs inflation model within supergravity that utilizes a fractional shift-symmetric Kähler potential to align with ACT data, simultaneously explaining the MSSM -term and achieving baryogenesis through non-thermal leptogenesis.
This study reveals that despite a large parameter space in hybrid hydrodynamic models, the shape of scaled transverse momentum spectra exhibits surprisingly limited flexibility and significant tension with momentum-integrated observables, particularly regarding the nucleon width parameter and bulk viscosity.
This paper proves the conjecture that eleven-dimensional supergravity admits an E11-invariant formulation with an infinite tower of higher dual fields by explicitly constructing parent actions at the linearised level, demonstrating that the resulting equations constrain Stueckelberg fields to ensure physical equivalence with the original supergravity fields while identifying their role as sources for Labastida tensors.
This paper introduces sign-problem-free qubit-regularized lattice gauge theories in the monomer–dimer–tensor-network basis that successfully reproduce the confined and deconfined phases and universality classes of conventional SU(N) theories, suggesting a viable nonperturbative pathway to defining continuum limits for Yang–Mills theory.
This paper establishes a unified semiclassical framework for the Reissner--Nordström black hole using Misner--Sharp--Hernandez mass quantization, which yields discrete mass spectra and Planck-scale corrections to thermodynamics that are encoded into a quantum-deformed geometry exhibiting modified surface gravities, stabilized inner horizons, and subtle shifts in observational signatures.
This paper presents a comprehensive lattice formulation of Dirac operator indices using -theory and spectral flow, which overcomes the limitations of the overlap Dirac operator by enabling applications to manifolds with curved boundaries and defining mod-2 indices in both even and odd dimensions.
