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 slides from a 2024 Simons Center talk that reviews the L-functional formalism and explores its potential applications to QED, linearized gravity, and quenched disorder, with a particular focus on addressing the infrared problem in QED through a conjectured infrared-finite perturbation theory.
This paper presents the exact closed-form expression for the three-loop (next-to-next-to-leading order) BFKL eigenvalue in planar N=4 super Yang-Mills theory at odd conformal spins, derived via direct Mellin extraction from the Caron-Huot-Herranen integrand and validated against Quantum Spectral Curve results up to spin 91.
This paper presents the closed-form expression for the three-loop BFKL eigenvalue in planar N=4 super Yang-Mills theory at odd conformal spins, derived from exact rational arithmetic and revealing a complex coefficient structure involving harmonic sums, polygamma transcendentals, and a proven arithmetic obstruction characterized by new prime denominators.
This paper develops a hypercomplex formulation of scalar electrodynamics with U(1)XSO(1,1) gauge symmetry that intrinsically generates dissipation, leading to the discovery that the system's thermodynamic constraints prohibit mixed states and force a discontinuous first-order phase transition, while also revealing structural instabilities when effective quartic couplings become negative.
This study analyzes the orbital dynamics, stability, and precession frequencies of test particles around a spinning, charged, quantum-corrected Einstein-Maxwell-dilaton black hole to determine how spin, charge, and quantum correction parameters modify spacetime geometry and circular orbit behavior near the event horizon.
This paper analytically derives the holographic timelike entanglement entropy for a boosted (1+1)-dimensional plasma in the AdS/CFT correspondence, revealing a critical boost velocity that triggers a transition from complex-valued extremal surfaces with universal imaginary contributions to purely real, spacelike-like saddles.
This paper proposes an ultralight dark matter model derived from a 5D gauge theory with Scherk-Schwarz twisted fermions, which generates repulsive self-interactions that govern the formation of astrophysical solitons for masses above eV while behaving as fuzzy dark matter for lighter masses.
This paper proposes a feasible experimental method to directly observe the Unruh effect by utilizing high acceleration gradients from wakefield accelerators and forward-beamed THz detectors to measure the thermal radiation of the Minkowski vacuum, distinguishing the signal from backgrounds via quantum detailed balance.
This paper extends timelike entanglement entropy to evaporating Schwarzschild--AdS black holes by deriving an adiabatic generalization of the Kruskal construction based on accumulated thermal phase, revealing how evaporation induces non-uniform Page-like times and memory-dependent dynamical entropy that tracks the entire evaporation history.
This paper re-evaluates the holographic proposal linking spread complexity to bulk radial momentum by demonstrating that while the relation holds for specific coherent states in de Sitter space, it generally fails in flat and de Sitter spacetimes where spread complexity primarily measures wave packet dispersion rather than classical momentum, indicating that a semiclassical limit alone is insufficient to establish a momentum-complexity correspondence.
