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 spherically symmetric regular black hole solutions sourced by anisotropic matter with a hydrodynamic equation of state, revealing that the pressure profile's behavior leads to hydrodynamic instabilities and subluminal constraints while establishing a universal hierarchy among the locations of strong energy condition violation, pressure roots, and pressure maxima.
This paper provides a systematic construction of Yangian descendant states for the Haldane-Shastry spin chain using the algebraic Bethe ansatz, enabling the derivation of explicit product and determinant formulae for their norms and overlaps.
This paper investigates high-frequency electromagnetic propagation in a rotating García--Díaz black hole coupled to nonlinear electrodynamics, demonstrating that the constitutive response induces birefringence that splits the spacetime's null cone into two effective optical metrics, resulting in distinct polarization-dependent critical contours on the observer's celestial sphere.
This paper demonstrates that in a nonlocal string field theory framework, Hawking radiation from a large black hole is exponentially suppressed and terminates shortly after the scrambling time due to the smearing of trans-Planckian interactions, resulting in a macroscopic remnant that offers a potential resolution to the black hole information paradox.
This paper presents a novel technique utilizing form factors and the universality of infrared divergences to compute new three-loop renormalization constants for the axial anomaly and pure-singlet contributions to the quark axial-vector form factor in a mixed gauge theory.
This paper argues that celestial operator product expansions (OPEs) require the inclusion of shadow-basis operators to ensure consistency, demonstrating that ordinary Mellin-basis exchanges are insufficient and that the resulting shadow-completed OPEs are fixed by universal shadow factors and verified through tree-level celestial amplitudes.
This paper introduces a quantum-information theoretic definition of many-body chirality as an obstruction to transforming a state into its complex conjugate via finite-depth local operations, demonstrating that stabilizer states of anyon theories exhibit this chirality and intrinsic imaginarity even when conventional diagnostics like modular commutators or chiral central charges vanish.
This paper employs the MSRDJ action formulation and generalized Galileon symmetry to demonstrate that Malthusian active flocks in two dimensions exhibit a line of fixed points and a marginal instability at , separating Gaussian and strongly interacting gapless phases that sustain long-range order through non-equilibrium critical behavior beyond the Wilson-Fisher paradigm.
This paper employs the method of images and Tseytlin's sphere prescription to derive the leading-order classical off-shell boundary action for the dilaton in half-space with Neumann boundary conditions, demonstrating that the resulting total action satisfies the requirements for a well-defined variational principle.
Using the method of images, this paper derives the first-order boundary term of the Einstein- action for a spherical worldsheet in a half-space, demonstrating that this specific boundary term ensures a well-posed variational principle for Dirichlet boundary conditions.
