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 explores a framework for gauge coupling unification using non-renormalizable operators in $SU(5)$, demonstrating that while fermion condensates in the 5 representation fail due to proton decay constraints, viable models achieving both unification and doublet-triplet splitting can be constructed using condensates in the 10 and 24 representations.
This paper presents new analytic Ricci-flat planar black hole and soliton solutions with primary scalar hair in asymptotically AdS space, demonstrating that these regular geometries undergo a first-order phase transition where the hairy soliton acts as the ground state, with the transition temperature and preferred phase window significantly influenced by the scalar hair parameter.
This paper investigates symmetry-resolved Krylov complexity in the Uncoloured Tensor Model, establishing conditions under which charge subspaces mirror the full-space complexity and demonstrating that the averaged complexity within symmetry subspaces is bounded by that of the full operator.
This paper presents Causal Dynamical Triangulations (CDT) as a nonperturbative lattice approach to quantum gravity that successfully demonstrates the dynamical emergence of a classical de Sitter-like universe from a sum over causal triangulations, while revealing unique short-scale properties such as a spectral dimension of approximately 2 and evidence for an ultraviolet fixed point.
This paper employs exact WKB analysis and resurgence theory to unify the quantization of non-Hermitian inverted triple-well systems, deriving exact median-summed spectra that clarify PT-symmetry breaking, characterize exceptional points via algebraic relations between bounce and bion actions, and demonstrate the complex conjugate relationship between resonance and anti-resonance spectra.
This paper establishes a fully field-theoretic derivation of chiral edge modes in abelian Chern-Simons theory on a strip by identifying general local boundary conditions that yield opposite Kac-Moody algebras and velocity-independent edge dynamics through a holographic-like bulk-boundary matching.
This paper calculates the resummed perturbative free energy of four-dimensional supersymmetric Yang-Mills theory to order in the 't Hooft coupling, demonstrating that all infrared divergences cancel, comparing different regularization schemes and Padé approximants, and showing that the theory exhibits superior convergence properties compared to QCD.
This paper demonstrates that artificial neural networks can accurately reconstruct bulk spacetime metrics from boundary entanglement entropy and Wilson loop data, effectively resolving degeneracies in finite-density holographic models and achieving sub-0.2% accuracy without relying on closed-form derivative relations.
This paper forecasts that space-based observations of extreme-mass-ratio inspirals by LISA can constrain near-horizon multipolar deformations at unprecedented precision levels, offering the first direct empirical tests to distinguish between classical Kerr black holes and quantum-gravity-inspired fuzzball geometries.
This paper establishes that emergent electric and magnetic 1-form symmetries in QED's soft sector generate an infinite-dimensional Abelian algebra with a central extension, which unifies asymptotic charges and soft photon theorems while determining specific contact terms in scattering amplitudes.
