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 constructs the first lattice model of the non-Abelian quantum double with exact electric-magnetic self-duality realized via lattice translation, revealing a gapless tetracritical Ising edge state and unifying the analysis of its topological phase transitions through category theory, microscopic Hamiltonians, and Chern-Simons-Higgs theory.
This paper investigates how 3-form dark energy coupled to photons via dimension-4 and dimension-6 operators can explain observed cosmic birefringence, revealing that while the dimension-4 operator offers a viable explanation sensitive to initial conditions, the dimension-6 operator requires unrealistically large couplings, with both scenarios producing birefringence profiles that can either mimic or be distinguished from axion-like particle models depending on early-universe field configurations.
This paper introduces a sign-orbit technique to systematically classify GOOFy-compatible quadratic structures in multi-Higgs models, demonstrating that such structures exist only under specific group-theoretic conditions and revealing that the renormalisation-group stability of the manifold is a unique consequence of algebra rather than a generic feature.
This paper investigates the reflected entropy and Markov gap for bosonic fields across event horizons in non-inertial frames and Schwarzschild black holes, revealing that while bosonic entanglement vanishes asymptotically, reflected entropy saturates at a non-zero floor and inter-wedge entropy diverges linearly with the squeezing parameter—a sharp contrast to the bounded behavior observed in fermionic systems.
This paper introduces an intrinsic measure of quantum information loss based on retrodiction failure, proves that its vanishing is equivalent to the Knill-Laflamme conditions for perfect quantum error correction via a concept termed "universal pristineness," and applies this framework to demonstrate asymptotic information retrieval in the Hayden-Preskill black hole evaporation model.
This paper proposes a unified framework where thermal relaxation of axions in an expanding plasma partitions dark matter into coherent and stochastic components, resulting in a relic population with lower mean momentum, reduced isocurvature, and distinct structural properties compared to standard equilibrium scenarios.
This paper proposes a new information-theoretic black hole entropy formula based on Kullback-Leibler divergence that resolves the conflict with the third law of thermodynamics while recovering the Bekenstein-Hawking area law as a high-temperature leading term.
This paper extends an information-theoretic black hole entropy, defined via Kullback-Leibler divergence and satisfying the Nernst third law, to charged and rotating Kerr-Newman cases while demonstrating that its thermodynamic properties can be reproduced by an infrared deformation of General Relativity that generates a small positive effective cosmological term.
This paper characterizes the full family of static, spherically symmetric axion-dilaton solutions in four-dimensional string theory as orbits of the FJNW solution and demonstrates that, unlike the Schwarzschild black hole which saturates the curvature threshold at the string-black-hole correspondence surface, all scalar-haired branches exhibit larger curvature diagnostics, though they may still remain under perturbative control in the weak-coupling regime.
This paper investigates the deformation of supersymmetric truly confining gauge theories by small anomaly-mediated supersymmetry breaking to identify their global symmetry breaking patterns, providing results that can be compared with lattice simulations of non-supersymmetric theories.
