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 Horizon Brightened Acceleration Radiation (HBAR) using derivative coupling between atoms and field momentum to resolve infrared divergences, revealing that point-like detectors exhibit frequency-independent transition probabilities due to local gravitational effects and that finite-size detectors may induce non-equilibrium thermodynamic states.
This paper introduces the cap amplitude as an expansion coefficient in one-matrix models and demonstrates that the dilaton equation and genus- free energy can be derived by gluing this amplitude to boundaries of the moduli space of Riemann surfaces.
This paper investigates the rich phase diagrams of Abelian gauge theories in 1+1 dimensions, including the Schwinger model, to establish a foundation for understanding symmetric mass generation in 2d chiral gauge theories where fermions acquire mass without breaking chiral symmetries.
This paper derives exact expressions for the statistics of correlations in large nonlinear recurrent neural networks with Gaussian quenched disorder using a path-integral approach, extending previous linear results to include nonlinear activation functions, systematic finite-size corrections, and new analytic predictions for colored noise.
The paper argues that while stationary black holes adhere to standard Bekenstein-Hawking thermodynamics, the evolving universe fundamentally requires a "teleodynamic" framework driven by horizon memory accumulation, thereby establishing a distinct thermodynamic regime for cosmology that challenges the extrapolation of black hole thermodynamics to the universe.
This paper derives recurrence relations for leading logarithmic all-loop quantum corrections in symmetric scalar field theories within curved spacetime, formulates a corresponding system of renormalization group equations for the effective potential in the large limit, and applies these results to analyze power-like potentials in the Jordan frame for inflationary cosmology.
This paper presents the first example of a nonlocal, Lorentz-invariant quantum field theory that simultaneously satisfies renormalizability, unitarity, and causality while violating CPT symmetry, offering a viable framework for explaining the universe's baryon asymmetry.
This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.
This paper demonstrates that the gauge dependence of one-graviton-loop corrections to the effective field equation of a massless, minimally coupled scalar in de Sitter space cancels out when contributions from all diagram classes, including one-loop corrections to external mode functions, are consistently collected, thereby supporting the construction of gauge-independent cosmological quantum-gravitational observables.
This paper provides a comprehensive review of supersymmetry, supergravity, and non-perturbative gauge theory dynamics, tracing the theoretical framework from fundamental algebraic structures and the Seiberg-Witten solution to string theory applications and a detailed analysis of the KKLT moduli stabilisation mechanism in the context of de Sitter vacua and the swampland conjecture.
