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 proposes that the ultra-high-energy gamma-ray emission from LHAASO J0341+5258 originates from cosmic rays escaping a past supernova remnant and illuminating nearby molecular clouds, a scenario that successfully explains the observed spectrum from GeV to TeV energies using both numerical simulations and analytical modeling.
This paper establishes a field-theoretic framework for temporal entanglement entropy in 2D conformal field theories via analytic continuation of twist correlators, which holographically identifies boundary-anchored complex geodesics as the relevant bulk saddles and confirms a complex extremal surface prescription that accurately reproduces field theory results across various excited states and quenches while uniquely determining the quantized imaginary part of the entropy.
This paper demonstrates that the Hyperbolic Ising model, a mixed-field Ising system defined on an AdS background with site-dependent couplings, exhibits faster scrambling dynamics and Lyapunov exponents consistent with the Maldacena-Shenker-Stanford bound compared to its flat counterpart, despite relying solely on nearest-neighbor interactions.
This paper proves that the existence of a contraction map is a necessary and sufficient condition for the validity of all linear holographic entropy inequalities with rational coefficients, demonstrating that non-contraction maps correspond to proper cubical subgraphs that manifest as bulk geodesic structure alterations violating the RT formula.
This paper investigates symmetry topological field theories (SymTFTs) of non-abelian and non-invertible symmetries by analyzing condensable algebras in Drinfeld centers to identify intrinsically gapless symmetry protected topological (igSPT) phases and demonstrate how embedding anomalous symmetries into larger fusion categories resolves categorical anomalies.
This paper formulates thermal quantum field theory on finite rotating boxes by demonstrating that consistent descriptions of finite rotations require space-time manifolds with non-trivial topologies distinct from the standard , implemented via rotated boundary conditions that restrict imaginary angular velocities to specific discrete values.
Using worldline quantum field theory and advanced computational techniques, this paper calculates conservative black hole scattering contributions at fifth post-Minkowskian and second self-force orders, resolving a spurious velocity divergence through a novel prescription to ensure consistency with radiative effects and post-Newtonian limits.
This paper analytically demonstrates that the temporal correlations arising from photon-graviton conversion in a magnetic field violate the Leggett-Garg inequality, offering a novel method to test the quantum nature of gravity.
This paper establishes a canonical link between quantum random walks on graphs and Krylov complexity to analytically derive Lanczos coefficients for the SYK model and fully characterize Krylov complexity on hypercubes, revealing that while Krylov complexity mimics black hole growth patterns, it saturates faster than circuit complexity due to quantum speed-up effects.
This paper presents the first full-color, three-loop QCD helicity amplitudes for Higgs boson plus three-parton scattering in the heavy-top effective theory, revealing that sub-leading color contributions are numerically significant and providing compact analytic expressions essential for precision LHC phenomenology.
