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.

Effective Field Theory for Superconducting Phase Transitions

This paper employs the Schwinger-Keldysh formalism to construct a symmetry-constrained effective field theory for s-wave superconducting phase transitions that reproduces Ginzburg-Landau equations, describes overdamped Higgs and absorbed phase modes near the critical point, and validates its structure and coefficients using holographic techniques to reveal complex relaxation dynamics characteristic of strongly coupled systems.

Detecting Symmetry-Resolved Entanglement: A Quantum Monte Carlo Approach

This paper introduces a quantum Monte Carlo approach for computing symmetry-resolved Rényi entropies in large-scale interacting systems by measuring disorder operators on replica manifolds, successfully validating theoretical predictions for entanglement equipartition in both the transverse-field Ising model and the Heisenberg chain across one and two dimensions.

Topological Effects in Neural Network Field Theory

This paper extends neural network field theory to topological settings by incorporating discrete parameters for topological quantum numbers, successfully recovering the Berezinskii–Kosterlitz–Thouless transition and verifying key aspects of T-duality in bosonic string theory, including momentum-winding exchange, Buscher rules, current algebra enhancement, and non-geometric T-fold transitions.

Spontaneous symmetry breaking in a non-Abelian topological gauge theory

This paper demonstrates that introducing a Fujikawa-type potential into a twisted N=2\mathcal{N}=2 super-Yang-Mills theory triggers spontaneous symmetry breaking in a non-Abelian topological gauge theory, generating massive vector bosons and fermions with correlated masses (mF=mB=vm_F = m_B = v) provided the gauge group is at least $SU(3)$ and three vacuum directions are utilized.

Black Hole Entropy and Complexity Growth in Horndeski Gravity within the AdS/BCFT Framework

This paper extends the AdS/BCFT correspondence to Horndeski gravity, demonstrating that the linear growth of holographic complexity and the switchback effect persist for rotating and charged black holes when the theory's effective causal structure aligns with the background metric, thereby supporting the "complexity=action" conjecture in scalar-tensor theories.

Three-point functions in critical loop models

This paper conjectures an exact formula for three-point functions of \ell-leg and diagonal fields in two-dimensional critical non-intersecting loop models, which is supported by agreement with Conformal Loop Ensemble results and numerical transfer matrix computations on cylindrical lattices, with minor discrepancies attributed to degenerate ground states in the Jones-Temperley-Lieb algebra.
