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 non-unitary field theories conjectured to be dual to cosmological correlators, scale invariance does not necessarily imply full conformal invariance (or bulk boost symmetry), a distinction illustrated using Einstein-Aether theory as a canonical example.
This paper investigates the phenomenological implications of a quantum-corrected Reissner-Nordström black hole by analyzing its orbital dynamics and quasi-periodic oscillations to constrain quantum parameters via observational data, while also examining scalar perturbations, greybody factors, and logarithmic thermal corrections to its entropy.
The paper refutes the assumption that exponentials of the d'Alembertian are positive-definite by demonstrating that such operators possess an infinite kernel of unstable solutions, thereby allowing arbitrary initial data over finite intervals and failing to resolve Ostrogradskian instabilities.
This paper establishes a correspondence between specific error-correcting codes over finite fields and the Narain lattices of heterotic string theories by demonstrating how Construction A and its variants can generate the and Spin lattices, while also elucidating the relationship between such codes and NSR-fermions.
This paper presents a theoretical model describing the dynamic non-equilibrium effects of external axion and inertial fields on systems of particles with spin, proposing the use of spin and current densities for detecting axion-like dark matter through a closed set of equations that incorporate spin-rotation coupling.
This paper utilizes gauge/string duality to investigate string breaking in spatial Wilson loops, specifically analyzing the influence of light flavors on the pseudopotential and estimating the spatial string breaking distance for $SU(3)$ gauge theory across temperatures from 0 to .
This Letter presents a formulation of transition matrix elements for PT-symmetric non-Hermitian Hamiltonians that ensures positivity and perturbative unitarity by utilizing a positive-definite inner product, and demonstrates its application to two-neutrino flavor oscillations and the seesaw mechanism.
This paper establishes a novel connection between conformal blocks and fractional calculus to derive the exact three-dimensional conformal block as a product of two hypergeometric 4F3 functions, thereby rigorously proving a decade-old conjecture by Hogervorst and offering new analytical tools for the conformal bootstrap.
This paper establishes a cosmological CPT theorem by demonstrating that a symmetry group, where any two discrete symmetries (including Reflection Reality and CRT) imply the third, allows for the non-perturbative determination of wavefunction coefficient phases in de Sitter spacetime without analytic continuation, thereby providing a powerful tool for de Sitter holography.
These Les Houches lecture notes, delivered in Summer 2024, provide an accessible, foundational introduction to the topological recursion framework, aiming to clarify its core concepts for readers encountering it across diverse fields like matrix models, string theory, and gauge theories without attempting to exhaustively detail every specific application.
