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 investigates how deviations from spherical symmetry in the -metric alter the properties of periodic orbits and their associated gravitational waveforms, demonstrating that precise measurements of waveform morphology from extreme-mass-ratio inspirals could constrain the deformation parameter .
This paper investigates the quantum Ising model on (2+1)-dimensional anti-de Sitter space using tensor networks to map its phase diagram, characterize boundary correlation scaling and entanglement entropy consistent with holography, and analyze scrambling behavior via out-of-time-ordered correlators.
This paper investigates the optical properties and Hawking radiation characteristics of Skyrmion black holes, demonstrating how the Skyrme term and geometric parameters influence the photon sphere, shadow shape, and energy emission spectra to provide potential observational signatures of nonlinear field effects in modified gravity.
This paper investigates the classical stability of a non-topological string in the minimal 331 model derived from an $SU(6)$ toy model and concludes that the string is only stable near the semilocal limit, suggesting such defects are unlikely to exist in unified theories based on $SU(N>5)$ Lie algebras.
This paper introduces a novel quantum relative-alpha-entropy that extends Umegaki's relative entropy beyond the traditional f-divergence framework, revealing a fundamentally geometric notion of quantum distinguishability characterized by nonlinear convexity, additivity, and an exact correspondence with classical relative-alpha-entropy via Nussbaum-Szkola distributions.
This paper demonstrates that tree-level amplitudes for Yang-Mills and Non-Linear Sigma Model theories are completely determined by the principles of locality, unitarity, and newly discovered hidden zeros, as evidenced by the successful reconstruction of their single- and double-soft theorems.
This paper initiates the integrability-based study of AdS/CFT dual pairs deformed by Groenewold-Moyal twists by constructing a coupled twisted spin-chain model, deriving its deformed spectrum via the Baxter equation, and successfully matching the leading energy terms with a non-local conserved charge derived from a deformed BMN string solution in the large- limit.
This paper demonstrates that the BEF symplectic form for non-local theories can be derived from an -Lagrangian via the covariant phase space approach, establishing its equivalence to the Barnich--Brandt form for second-order theories and providing a unified framework for understanding corner terms, boundary conditions, and Hamiltonians.
Using the Bethe Ansatz, this paper reveals a novel phase between the Kondo and unscreened phases in the non-Hermitian Kondo model, demonstrating that dissipation drives a phase transition characterized by distinct time scales and a generalized Kondo temperature.
This paper utilizes the Symmetry TFT framework to establish a one-to-one correspondence between higher representations of defect operators and gapped boundary conditions, providing a streamlined method for characterizing defect charges across various dimensions and applications.
