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 proposes a new super-renormalizable or finite non-local ultraviolet completion of general inflationary theories that preserves their classical background solutions and perturbation dynamics, thereby resolving previous conflicts between renormalizability and stability while demonstrating the consistency of the inflationary paradigm with a well-defined quantum theory of gravity.
This paper investigates the Higgs branches and associated vertex operator algebras (VOAs) of 4d SCFTs engineered from IIB superstring theory on canonical threefold singularities, deriving new examples with E-type Kleinian singularities, proposing conjectures for their affine W-algebra VOAs, and analyzing Schur indices through BPS quivers and deformed singularities.
Using first-principles lattice simulations of SU(3) Yang-Mills theory in Rindler spacetime, this study demonstrates that weak acceleration induces a spatially inhomogeneous confinement-deconfinement phase transition where distinct phases coexist, with a phase boundary consistent with theoretical predictions and a critical temperature matching that of non-accelerated gluodynamics.
This paper demonstrates that perturbatively irrelevant operators, such as four-fermion interactions, can become relevant in the infrared due to an IR Landau pole arising from an infinite number of modes in the RG flow rather than singular loop corrections.
This paper proves that scale-invariant one-loop corrections to superhorizon curvature perturbations from small-scale scalar modes are absent in general inflationary scenarios, including transient ultra-slow-roll, due to dilatation symmetry and explicit one-loop calculations within an in-in effective field theory framework.
This paper derives a systematic framework for one-loop effective potentials in curved spacetimes and demonstrates that, for scalar theories in de Sitter and anti-de Sitter backgrounds, the computed -functions and anomalous mass dimensions coincide exactly with their flat-space counterparts despite significant curvature-induced modifications to physical masses and couplings.
This paper investigates mixed-state phases obtained by tracing out the bulk of higher-order subsystem SPTs protected by non-invertible Kramers-Wannier symmetries, revealing a "doubled average SPT" phase characterized by the coexistence of topological order and symmetry breaking that is diagnosed using interface probes.
This work generalizes the relationship between star-exponentials and quantum propagators to fermionic systems within deformation quantization, deriving a fermionic Feynman-Kac formula for ground state energy calculation and validating the method using harmonic and driven Fermi oscillators.
This paper investigates the scalar curvature of the vector moduli space in 5d supergravities derived from M-theory compactifications, demonstrating that curvature divergences occur exclusively at points where gauge interactions become infinitely strong, leading to decoupled superconformal field theories or little string theories, with specific conditions for rank theories and decompactification limits involving 6d SCFTs.
This paper derives four-derivative corrections to the heterotic Kerr-Sen black hole solution via field redefinitions and boosts, demonstrating that the resulting distinct multipole moments offer a potential experimental signature to differentiate string theory from Einstein-Maxwell theory in gravitational wave data.
