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 demonstrates that generalized symmetries, including higher-form, subsystem, gauge, and non-invertible symmetries, can induce exponential Hilbert space fragmentation, thereby challenging the assumption that such fragmentation necessarily implies ergodicity breaking and revealing its role in disorder-free localization.
This paper proposes that the universal galactic acceleration scale arises from a trace-anomaly-induced infrared spectral gap in a coherent, color-neutral gluonic dark sector governed by Anti de Sitter symmetry, which generates a characteristic acceleration scale within standard Newtonian gravity without requiring modified gravity or specific formation histories.
This paper demonstrates that the state-counting interpretation of black hole entropy and the unitary Page curve for Hawking radiation are equivalent within the gravity path integral framework, showing that the information loss paradox is resolved by any microstate basis compatible with black hole entropy via a convex optimization problem for von Neumann entropy.
This paper computes the energy density of scalar-tensor-induced gravitational waves (STGWs) generated during early matter-dominated and radiation-dominated eras, demonstrating that while these signals dilute in a purely matter-dominated universe, they remain viable and potentially dominant contributors to the nanohertz stochastic gravitational wave background observed by NANOGrav and detectable by the future Square Kilometre Array.
This paper presents a systematic calculation of non-dissipative, quantum-origin second-order hydrodynamic corrections to the stress-energy tensor and currents for free boson and Dirac fields in thermal vorticity, deriving their Kubo formulae via equilibrium correlators and demonstrating that the axial current receives vorticity-proportional corrections independent of anomalous terms.
The paper demonstrates that the standard low-energy effective field theory of quantum gravity predicts unobservably small vacuum fluctuations in interferometers, implying that any future detection of large gravitationally-induced length variations would signal a fundamental breakdown of this theory.
This paper proposes an alternative resolution to the black-hole information paradox by suggesting that trans-Planckian effects in string theory cause Hawking radiation to cease around the scrambling time, leaving the black hole predominantly classical with negligible energy loss.
This paper investigates normal mode analysis in relativistic massive transport by demonstrating how particle mass induces coupling between sound and heat channels, alters the branch cut structure responsible for Landau damping, and leads to non-monotonic dependencies in the critical wavenumbers for collective modes.
This paper derives the general non-holomorphic completion for the generating series of BPS indices in Type II Calabi-Yau string compactifications by evaluating the refined Witten index of multi-center supersymmetric quantum mechanics via localization, thereby confirming that the required generalized error functions arise from the spectral asymmetry of scattering states for an arbitrary number of BPS dyons.
This paper classifies positive traces on the Coulomb branch algebras of specific three-dimensional and four-dimensional gauge theories, focusing on quantizations of type Kleinian singularities and algebras associated with pure and gauge theories.
