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 establishes the stability of the vacuum and constructs consistent quantum dynamics for scalar and Maxwell fields in Anti-de Sitter spacetime by demonstrating that constraints and anti-commutation relations eliminate unbounded negative energy spectra, thereby ensuring a finite, renormalized energy-momentum tensor and a stable vacuum that respects AdS symmetry.
This paper investigates the impact of topology on classical mechanics by analyzing the formalism of Bering to derive and solve boundary-corrected Klein-Gordon equations on finite spaces across various dimensions.
This paper demonstrates that while two distinct theoretical descriptions of massive spinning fields during inflation yield identical signatures in the inflaton bispectrum due to the exclusive propagation of helicity-zero modes, they become distinguishable at the level of the trispectrum and higher-point correlation functions.
This paper derives new closed-form expressions for the partition functions of free conformally-coupled scalars in even dimensions by identifying them with multiple elliptic Gamma functions, whose modular properties are utilized to resum high-temperature expansions and provide a geometric interpretation within superconformal field theory.
This paper presents a novel all-order momentum-space prescription for systematically identifying facet regions in massless wide-angle scattering using a combination of graph theory and convex geometry, thereby resolving long-standing questions about region determination in asymptotic expansions and revealing the non-distributive lattice structure of momentum modes.
This paper demonstrates that a magnetic field induces effective dispersion in an exactly flat band through quantum geometric quantities (orbital moment and a second-order susceptibility), thereby enabling a modified orbital magnetic response and a de Haas-van Alphen effect characterized by emergent Fermi surfaces and a quadratic level spacing.
This paper develops a path integral formalism for calculating the entanglement entropy of finite gravitating regions at time symmetry, interpreting the result as the minimal generalized entropy of enclosing regions and proposing a concept of "terrestrial holography" where interior spatial regions encode larger volumes, contrasting with standard boundary-based holography.
This paper utilizes tree-level factorization, supersymmetry, and positivity constraints to demonstrate that the low-energy effective action of four-dimensional Yang-Mills theory coupled to supergravity is uniquely localized to the heterotic string trajectory, effectively ruling out alternative infinite-spin-tower models.
This paper demonstrates that finite-string-length effects in the near-horizon geometry of near-extremal NS5 branes nonperturbatively resolve the bouncing singularity found in the supergravity limit, rendering the time-domain reflection amplitude an entire function of complex time.
This paper demonstrates that Jackiw-Teitelboim gravity with a positive cosmological constant yields a flat probability distribution for the size of expanding de Sitter universes through holography-consistent double-trumpet amplitudes, contrasting with the suppression of large universes predicted by no-boundary wavefunctions.
