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 investigates thermal out-of-time-order correlators in magnetic billiards, specifically the stadium geometry, to map the crossover between quantum chaos and magnetic rigidity as a function of temperature and magnetic field strength, while demonstrating that guiding-center operators exhibit distinct non-exponential dynamics.
This paper demonstrates that tree-level cosmological correlators in de Sitter space can be systematically reconstructed from their discontinuities using momentum-space dispersion relations and cutting rules, thereby deriving dressing rules that connect these correlators to flat-space Feynman diagrams while emphasizing the fundamental role of unitarity.
This paper, the fifth in the En series, extends the EP exotic invariant model introduced in the previous E4 paper by incorporating a U(1) gauge theory.
This paper provides a physical interpretation for the analytic continuation of the superconformal SU gauge theory partition function on the four-sphere by demonstrating that its singularities arise from two-dimensional unstable instantons associated with 4d complex saddles, a result derived from the chiral algebra subsector and consistent with Higgs branch localization.
This paper proposes using Bose-Einstein condensates interacting with quantized gravitational waves to derive a quantum gravitational Fisher information metric, revealing that high graviton squeezing enables finite measurement precision at zero time and mitigates decoherence effects.
This paper extends the pragmatic mode-sum regularization method to the interior of a Kerr black hole by introducing a novel intermediate divergence subtraction to handle the divergence of the multipolar sum, thereby enabling the calculation of renormalized quantum fluxes and field squares for a massless scalar field in the Unruh state from the event horizon to the inner horizon.
This paper extends the universality of quantum thermalization by demonstrating that the subsystem thermalization hypothesis holds generically for small subsystems in quantum spin chains with various symmetries, not only for standard thermal ensembles but also for generalized and partial Generalized Gibbs Ensembles (p-GGEs) that incorporate partial sets of conserved charges.
This paper investigates a Hermitian matrix model modified by a curvature term that breaks unitary invariance, demonstrating through analytical and numerical methods that this modification suppresses the noncommutative striped phase and shifts the triple point toward renormalizable behavior in the large- limit while revealing a novel multi-cut phase at finite matrix sizes.
This paper constructs local commuting projector lattice models in (2+1)D and (3+1)D that realize nonzero generalized Hall conductivities for ordinary and higher-form continuous symmetries by utilizing a standard toric code with non-onsite symmetries, thereby circumventing traditional no-go theorems while supporting protected gapless boundaries consistent with continuum field theories.
By applying the Hawking Area Theorem, validated through gravitational wave data, as a consistency criterion for black hole entropy corrections, this study derives constraints on the spin-parity and number of Beyond-Standard-Model particle species that may serve as dark matter candidates.
