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 quantizes the Friedberg-Lee-Pang-Ren (FLPR) model using the Batalin-Fradkin-Vilkovisky formalism to construct BRST charges and invariant effective actions in both polar and Cartesian coordinates, while also establishing finite field-dependent BRST symmetries that link the gauge-fixed and classical gauge-invariant actions.
This paper analyzes pole skipping in the stress tensor two-point functions of two-dimensional quantum field theories perturbed by relevant deformations, proposing a method to resolve singular expressions in conformal perturbation theory and demonstrating precise agreement between the resulting Lyapunov exponents and butterfly velocities with both Ward identity calculations and holographic duals.
This paper demonstrates that a -invariant Lagrangian perturbed by a complex, -symmetric anisotropy yields real critical exponents in both broken and unbroken phases, with the most stable fixed point flowing to an effectively Hermitian symmetric system, thereby showing that Hermiticity and symmetry can emerge as intrinsic features of inherently non-Hermitian theories.
This paper establishes a general, gauge-invariant framework within the covariant phase space formalism for deriving the first law of black hole mechanics in generic diffeomorphism-invariant theories, specifically addressing dynamical perturbations of charged black objects with non-minimally coupled -form gauge fields and resolving ambiguities in defining electric and magnetic charges and dynamical entropy.
This paper investigates universal features of chiral symmetry breaking in large- QCD by comparing non-perturbative lattice Monte Carlo calculations of the low-lying Dirac spectrum with chiral Random Matrix Theory predictions, utilizing twisted volume reduction to reach and extract the large- chiral condensate.
This paper develops a consistent field-based perturbation framework to analyze the impact of oscillating generalised axion-like quintessence fields on cosmic structure growth, demonstrating that the standard effective fluid description fails during this dynamical phase.
This paper demonstrates that in pure 2D JT gravity, non-perturbative corrections arising from negative energy states in the dual random matrix ensemble cause a dramatic breakdown of the semiclassical bulk geometry at parametrically shorter length scales () than previously predicted ().
This paper establishes a duality between Hořava-Witten theory on the wedge sum of two circles () and type 0B orientifolds, providing a geometric explanation for the gauge group doubling and revealing novel M-theoretic degrees of freedom at the junction point.
This paper establishes the typicality of bipartite entanglement in one-dimensional anyon chains by deriving analytical expressions for average entropy and variance, revealing a unique topological Page curve asymmetry and demonstrating that chaotic eigenstates align with Haar-random predictions.
This paper employs Tomita-Takesaki modular theory and the Bisognano-Wichmann results to construct wedge-localized vectors in the one-particle Hilbert space of a relativistic massive scalar field in 1+1 dimensions, thereby analyzing Bell-CHSH inequality violations for various operators and outlining a path toward saturating Tsirelson's bound.
