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.

This paper demonstrates that non-Clifford gates essential for universal quantum computation, such as the Ising interaction, Toffoli, and T gates, arise naturally as path integrals in various topological quantum field theories, with their specific magic-generating properties determined by the underlying algebraic data and topological structures of the theories.
This paper generalizes quantum gate complexity and geometric distance measures to non-invertible symmetries in quantum field theories, demonstrating that such symmetries define parallel computation schemes involving post-selection and revealing that their simple objects can be computationally highly complex.
This paper demonstrates that by utilizing exact finite-temperature saddles and a Picard-Lefschetz contour integral framework involving Weierstrass elliptic functions and Lamé operators, one can systematically compute the full resurgent structure of the double-well partition function and energy levels for all excited states, thereby overcoming the limitations of the traditional dilute instanton gas approximation.
This paper establishes a comprehensive framework connecting intrinsic Carrollian fermions, small speed-of-light expansions of relativistic Dirac theory, and light-cone dynamics by deriving Carrollian actions from relativistic limits and demonstrating how Carrollian fermions in dimensions relate to relativistic fermions in both and dimensions.
This paper derives analytical expressions for the one-loop quantum corrections to the Casimir effect and topological mass generation for a self-interacting real scalar field between rough parallel plates at low temperatures, utilizing WKB methods and -function regularization to account for both geometric perturbations and finite thermal effects.
This paper establishes a rigid superspace framework using a spurion superfield to systematically identify half-BPS spatially inhomogeneous impurity backgrounds in dimensions, deriving the corresponding BPS equations and energy bounds while addressing obstructions caused by explicit coordinate and derivative-dependent couplings.
This paper demonstrates that the thermality of the Unruh effect breaks down in null-shifted Rindler wedges for massive scalar and Dirac fields, as the mass term disrupts the conformal symmetry required for the characteristic exponential frequency mixing, resulting in a nonthermal response where the massive field remains unexcited.
This paper demonstrates that Many-Body Gravity (MBG), a modified 5-D gravity theory, naturally reproduces cosmic inflation and resolves time-definition issues in non-interacting universes by utilizing entropic terms and interacting massless scalar fields, all without requiring dark matter.
This paper demonstrates that in the low-energy supergravity treatment of type IIB string theory on D-instanton wormhole profiles, the modes of broken local supersymmetry in the bulk generate non-vanishing fermionic diagonal modes on the boundaries via current-current two-point functions, extending these results to multi D-instanton and general Euclidean brane scenarios.
This paper establishes the equivalence between double-scaled fermionic and bosonic embedded ensembles and the complex Sachdev-Ye-Kitaev model by utilizing the Wick product of non-commuting Gaussian variables to derive spectral and correlation functions, thereby revealing a duality between model moments and expectation values in a chord Hilbert space.
