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 presents a solvable 3+1d lattice boson model that realizes exact chiral symmetry, evading Nielsen-Ninomiya no-go theorems to reproduce continuum features such as the chiral anomaly, axion-like couplings, and non-invertible or 2-group symmetries upon gauging.
This paper argues that commercial quantum computers projected to exceed 1600 logical qubits will operate beyond classical Planck-scale limits, providing a feasible experimental test to resolve the incompatibility between general relativity and quantum mechanics.
This paper derives finite- formulas for the supersymmetric indices of M5-branes on toric Sasaki-Einstein manifolds and M2-branes probing toric Calabi-Yau four-folds using equivariant integration, revealing a shared mathematical structure that motivates a new duality exchanging the worldvolume and transverse geometries of these brane systems.
This paper demonstrates that a massless scalar field on a two-dimensional non-singular black hole spacetime exhibits a non-vanishing probability for particles to tunnel from the causally disconnected interior of the inner horizon to the exterior of the outer horizon, with the total probability asymptoting to a maximal value determined solely by the surface gravities of the two horizons.
This paper constructs a new class of traversable double-throat wormhole solutions in a string cloud background, demonstrating that the inter-throat region can be supported by non-exotic matter while localizing Null Energy Condition violations to the throat vicinities.
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 investigates massive modes on a magnetized blow-up manifold of , establishing that smooth connections between the orbifold and require the invariance of total magnetic flux, total curvature, and effective magnetic flux, while revealing that the number of localized modes at each singularity increases by one for each unit increment in the mass level.
This paper demonstrates that classical-quantum dynamics can emerge generically as an effective, non-Markovian description of fully quantum systems undergoing decoherence, implying that experimental agreement with such models does not definitively prove the mediator is fundamentally classical.
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 macroscopic observables can obey arbitrary linear evolution equations, including those appearing acausal, by constructing a causal and covariantly stable kinetic model where the dispersion relation is encoded entirely in the initialization of microscopic degrees of freedom, thereby challenging the notion that microscopic causality alone constrains the analytic form of dispersion relations at real wavenumbers.
