hep-th papers | Gist.Science

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.

HyperPrecision: A Mathematica package for High-Precision Numerical Evaluation of Multivariate Hypergeometric Functions

This paper introduces HyperPrecision, a Mathematica package that enables high-precision numerical evaluation of multivariate hypergeometric functions and their Laurent expansions by automatically constructing Pfaffian systems, reducing them to ordinary differential equations along a contour, and solving them via the Frobenius method to overcome convergence limitations in physics and mathematics applications.

Primary Constraints of Newer General Relativity

This paper analyzes the primary constraint structure of Newer General Relativity by performing a fully nonlinear decomposition of its Lagrangian, recovering known tensor and vector constraints while identifying a previously unreported degeneracy in the scalar sector that yields one or two additional constraints depending on the theory's parameters.

Late-time Quantum Vacuum Decay and its Cosmological Implications

This paper investigates the cosmological signatures of late-time quantum vacuum decay, demonstrating that precision distance measurements and CMB anisotropy data can constrain or detect transitions that alter vacuum energy and convert dark matter, with specific models offering a potential resolution to tensions within the standard $\Lambda$ CDM framework.

Non-onsite symmetry breaking: topological phase coexistence and criticality

This paper investigates the spontaneous symmetry breaking of non-onsite symmetries in one and two spatial dimensions, revealing novel phases characterized by the coexistence of distinct symmetry-protected topological orders, long-range entanglement, and topological quantum criticality.

Quantum Cellular Automata on Symmetric Subalgebras

This paper establishes a complete classification of one-dimensional quantum cellular automata restricted to symmetric subalgebras under finite Abelian group symmetries, demonstrating that they are characterized by anyon permutation symmetries and a generalized GNVW index, which reveals that certain dualities like Kramers-Wannier cannot be extended to the full operator algebra due to their irrational indices and nontrivial mixing with lattice translations.

The Mechanism behind the Information Encoding for Islands

This paper elucidates the mechanism behind the nonlocal information encoding of entang islands in a manifestly local theory by demonstrating that the effective mass of the graviton in island models, specifically within the Karch-Randall braneworld, enables the interior information of black holes to be encoded in early Hawking radiation.

Local Expansion Mechanisms for Quantum-Scale Wormholes

This paper proposes a refined "local inflation bubble" mechanism to theoretically expand Planck-scale quantum wormholes into macroscopic structures within an inflationary de Sitter background, while calculating the specific stress-energy requirements and intrinsic lower bounds for the exotic matter needed to sustain such a bubble.

Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies

This paper demonstrates that in both Loop Quantum Cosmology and its modified variant, a combined potential featuring an ekpyrotic component can effectively suppress shear during the bounce to resolve anisotropy issues, while subsequently allowing the inflationary component to dominate and produce a sufficiently long inflationary phase.

The dark dimension, proton decay, and the length of the M-theory interval

This paper demonstrates that proton decay constraints severely limit the size of the M-theory interval in $E_8\times E_8$ heterotic string theory, ruling out the possibility of a micron-scale dark dimension and restricting its length to approximately $10^{-28}$ meters or smaller.

Monodromy Defects in Maximally Supersymmetric Yang-Mills Theories from Holography

This paper investigates holographic duals of codimension-2 supersymmetric defects in maximally supersymmetric Yang-Mills theories by constructing Type II supergravity solutions from branes wrapping spindle configurations, deriving a prescription for defect entanglement entropy that scales with the ambient free energy, and distinguishing these defect solutions from circle compactifications in the D5-brane case.
