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.

Hodge Atoms at Conifold Degenerations: F-Bundles, Limiting Mixed Hodge Modules, and the Rigid-Flexible Decomposition

This paper extends the Hodge atoms framework to one-parameter conifold degenerations of Calabi–Yau threefolds by establishing a canonical rigid-flexible decomposition of the degeneration atom and proving a Stokes–Extension Identification that links the Stokes matrix of the Dubrovin connection to the variation morphism in mixed Hodge module theory.

Adiabatic continuity in a partially reduced twisted Eguchi-Kawai model with one adjoint Dirac fermion

This paper provides numerical evidence from a partially reduced twisted Eguchi-Kawai model that the confined phase of large-NN $SU(N)$ gauge theory with one adjoint Dirac fermion persists under spatial compactification with periodic boundary conditions, supporting an adiabatic continuity scenario between large and small circles, whereas antiperiodic boundary conditions induce a clear deconfinement transition.

Ground state preparation in two-dimensional pure Z2\mathbb{Z}_2 lattice gauge theory via deterministic quantum imaginary time evolution

This paper demonstrates that a generalized, gauge-invariant deterministic quantum imaginary time evolution (QITE) algorithm can efficiently prepare the ground state of two-dimensional pure Z2\mathbb{Z}_2 lattice gauge theory with high accuracy (relative error < 0.1%) and reduced resource costs, as validated by classical tensor network simulations against DMRG results.

Yukawa scalar self energy at two loop and ϕ2\langle \phi^2 \rangle in the inflationary de Sitter spacetime

This paper computes the two-loop Yukawa scalar self-energy and the resulting loop-corrected coincident two-point correlation function ϕ2\langle \phi^2 \rangle in inflationary de Sitter spacetime, demonstrating that the leading secular growth scales as ln4a\ln^4 a and yields a bounded, monotonically decreasing expectation value that implies an increasing dynamically generated scalar mass with stronger coupling.

Leading UV divergences of quantum corrections to Kähler superpotential in general N=1\mathcal{N}=1 chiral model

This paper utilizes the Bogoliubov-Parasiuk theorem to derive differential equations governing the sum of leading ultraviolet divergences for the Kähler potential in general N=1\mathcal{N}=1 supersymmetric chiral theories, thereby extending results from renormalizable Wess-Zumino models to include non-renormalizable interactions.

Bounding relative entropy for non-unitary excitations in quantum field theory

This paper utilizes the convexity of non-commutative LpL^p norms to establish a general bound on the relative entropy between a faithful state and arbitrary excitations in von Neumann algebras, including type III algebras relevant to quantum field theory, without requiring knowledge of the relative modular operator, and applies this result to prove the uniform boundedness of relative entropy for single-particle excitations of the chiral current.
