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 a quartic spin-spin interaction can generate a microscopic source for axial torsion through vacuum condensation, which in turn modifies neutrino oscillations by introducing spin-dependent frequencies and CP asymmetries.
This paper demonstrates that the first-order Goldberg-Palatini gravitational action can be uniquely reconstructed from Noether identities associated with diffeomorphism invariance by imposing polynomiality and dimensional constraints on a symmetric metric perturbation and trace-adjusted connection, thereby eliminating the ambiguity inherent in self-coupling approaches without requiring a predefined energy-momentum tensor.
This paper investigates the spatial decay of stabilizer Rényi moments in critical quantum chains described by two-dimensional conformal field theories, demonstrating that these moments depend on operator basis choices rather than just entanglement spectra, and provides exact results for pure stabilizer states and Ising models that reveal how on-site rotations alter decay exponents while preserving entanglement spectra.
This paper analyzes non-minimal unimodular inflation in the Einstein frame, deriving its exact analytical observables and demonstrating that while the model can reproduce acceptable CMB parameters at isolated field values, it fails to satisfy both scalar weak gravity conjectures and cannot simultaneously fulfill the refined de Sitter conjecture while supporting a complete 50–60 e-fold inflationary history.
This paper demonstrates that the axion dark energy model, characterized by a periodic scalar-field potential, is a dynamically consistent and observationally viable candidate for cosmic acceleration because its background evolution naturally transitions from saddle-point radiation and matter epochs to a stable dark energy attractor.
This paper extends the recursive construction of free-field realizations to supersymmetric -algebras associated with the Lie superalgebras and , providing explicit realizations for specific cases including new results for and , and utilizing these to compute central charges, conformal weights, and construct local integrals of motion.
This paper investigates surface defects in four-dimensional and class theories on lens spaces by deriving closed-form difference operators that generate a Sklyanin algebra and proposing that these operators correspond to transfer matrices of inhomogeneous spin chains.
This paper employs neural networks within a crossing-symmetric dispersion relation bootstrap framework to simultaneously learn the mass spectrum and partial-wave coefficients of tree-level open superstrings, deriving bounds on Wilson coefficients and identifying the Virasoro-Shapiro amplitude while analyzing transitions in non-dual amplitudes.
This paper investigates the bulk-boundary structure of by distinguishing between a global topological Euler relation and a local Pontryagin-Cotton relation, demonstrating that the normalizable metric coefficient and the Cotton tensor do not contribute linearly to the finite Euler boundary term, thereby clarifying the mechanisms of holographic reconstruction from broken conformal gauge symmetry.
This paper demonstrates that the Yamazaki-Hori solution to the Ernst equation can be expressed in Pfaffian form, a result that sheds new light on Nakamura's conjecture regarding the relationship between the Ernst equation and the 2D Toda model.
