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.

Generalized PT-symmetric nonlinear Dirac equation: exact solitary waves solutions, stability and conservation laws

This paper derives exact solitary wave solutions for a generalized $\mathcal{PT}$ -symmetric nonlinear Dirac equation with power-law scalar-scalar interactions, demonstrating that while energy and momentum are conserved despite gain-loss effects, the $\mathcal{PT}$ -transition point is determined by solution existence rather than nonlinearity strength, and that higher-order nonlinearities combined with gain-loss mechanisms restrict the stability domain of these solutions.

The Cohomology of Solvmanifold SYZ Mirrors

This paper investigates non-Kähler SYZ mirror symmetry for solvmanifolds by establishing the correspondence between supersymmetric cycles via Fourier-Mukai transforms, deriving Lie-theoretic criteria to construct and classify explicit mirror pairs from almost abelian and nilpotent Lie groups, and elucidating the role of Tseng-Yau cohomology through its connection to noncommutative geometry.

Spatially modulated instabilities of an AdS black hole

This paper investigates perturbative instabilities of an AdS black hole within an Einstein-Maxwell theory derived from N=2, D=5 supergravity, demonstrating that the inclusion of gauge and mixed gauge-gravitational Chern-Simons terms leads to momentum-dependent instabilities below a critical temperature, resulting in a spatially modulated solution characterized by a bell-curve phase diagram.

Extrinsic geometry and Hamiltonian analysis of symmetric teleparallel gravity

This paper derives generalized Gauss-Codazzi relations and boundary terms for non-metric geometry to construct the Hamiltonian of symmetric teleparallel gravity, thereby proving it possesses the same number of degrees of freedom as General Relativity.

On Generalized Statistics and Stability in $\mathbb{Z}_2^2$ -Graded Supersymmetric Yang-Mills Theory

This paper constructs a classical minimal $\mathbb{Z}_2^2$ -graded supersymmetric Yang-Mills theory and demonstrates its stability through correct kinetic term signs and a positive Hamiltonian, thereby proving that $\mathbb{Z}_2^2$ -graded generalized statistics can be realized in a stable interacting supersymmetric gauge theory.

From Finite-Node Conifold Geometry to BPS Structures I: Algebraic State Data

This paper extracts and formalizes the intrinsic algebraic state data $(V_\Sigma, E_\Sigma, c_\Sigma)$ associated with finite-node conifold degenerations by demonstrating that the corrected perverse sheaf, its mixed-Hodge-module refinement, and its schober realization all share a unified finite-node architecture, thereby establishing the foundational algebraic layer for subsequent BPS and wall-crossing structures.

Dai-Freed anomalies and level matching in heterotic asymmetric orbifolds

This paper interprets the standard consistency conditions for asymmetric heterotic orbifolds, specifically level matching and mod-2 constraints, as the vanishing of worldsheet Dai-Freed anomalies by computing spin-bordism invariants and analyzing higher-genus partition functions.

Finite-density equation of state of hot QCD using the complex Langevin equation

This paper presents continuum-extrapolated lattice simulations of hot QCD at the physical point using the complex Langevin equation to determine the equation of state at unprecedentedly high baryon densities, demonstrating controlled convergence and agreement with previous lattice and perturbative results.

Unitarity Quadratic Quantum Gravity in 4D

This paper demonstrates that unitarity is preserved in four-dimensional quadratic gravity with a positive Weyl squared coefficient by proving that the extra spin-2 sector corresponds to a dual inverted harmonic oscillator rather than a ghost, thereby satisfying the optical theorem and ensuring renormalizability without asymptotic states.

Bootstrapping Tensor Integrals

This paper introduces a bootstrapping methodology combining Dyson-Schwinger equations and positivity constraints to efficiently approximate moments of large- $N$ random $U(N)^D$ invariant tensor models, successfully validating the approach on quartic and hexic rank-three models and proposing new explicit formulae for the quartic case.
