hep-th papers | Gist.Science

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.

Explicit decoders using fixed-point amplitude amplification based on QSVT

This paper presents two explicit quantum circuit decoders—the generalized Yoshida-Kitaev decoder and a Petz-like decoder—that utilize fixed-point amplitude amplification based on quantum singular value transformation to reliably recover quantum information from arbitrary noisy channels when the decoupling condition is satisfied, thereby achieving communication rates arbitrarily close to the quantum capacity with significantly reduced computational complexity compared to previous methods.

Gauge theory and mixed state criticality

This paper establishes a framework for constructing strong symmetry-breaking phases and their associated criticalities in mixed quantum states by utilizing the ground states of lattice gauge theories as their purified counterparts, thereby introducing new mixed-state topological phases and providing a method to study quantum operations between them.

Boundary topological orders of (4+1)d fermionic $\mathbb{Z}_{2N}^{\mathrm{F}}$ SPT states

This paper investigates (3+1)d topological orders with anomalous $\mathbb{Z}_{2N}^{\mathrm{F}}$ symmetry by microscopically constructing symmetry-preserving gapped boundary states for related (4+1)d SPT phases, demonstrating that such states admit a topological $\mathbb{Z}_4$ gauge theory description when $N=\nu$ , a non-TQFT solution when $\nu=N/2$ , and no symmetric gapped state otherwise, thereby confirming existing no-go theorems.

Nonlinear soft mode action for the large- $p$ SYK model

This paper provides two distinct derivations of the full nonlinear Schwarzian effective action governing the low-temperature soft mode of the large- $p$ SYK model and its chain generalization, demonstrating that these effective descriptions can be rigorously derived from microscopic dynamics without relying on additional assumptions or matching procedures.

Bound states of quasiparticles with quartic dispersion in an external potential: WKB approach

This paper formulates a WKB approach for quasiparticles with quartic dispersion, demonstrating that higher-order Airy-type functions and their hyperasymptotic corrections are essential for matching wave functions at turning points, leading to a generalized Bohr-Sommerfeld quantization condition that includes non-perturbative corrections even in the absence of tunneling.

Ordering the topological order in the fractional quantum Hall effect

This interdisciplinary paper proposes that the one-form global symmetry and its anomaly serve as a unifying organizing principle to constrain and uniquely identify the minimal topological orders underlying various fractional quantum Hall systems based on their Hall conductivity.

A stringy dispersion relation for field theory

This paper derives a novel, local, and crossing-symmetric dispersion relation for 2-2 scattering amplitudes motivated by string theory, demonstrating its utility in bounding Wilson coefficients for gravitational effective field theories and providing convergent series representations for Veneziano, Virasoro-Shapiro, and multi-variable generalizations.

Quivers and BPS states in 3d and 4d

This paper proposes and rigorously establishes a symmetrization relation between 4d $\mathcal{N}=2$ BPS quivers and 3d $\mathcal{N}=2$ symmetric quivers, demonstrating that the wall-crossing structure of 4d Argyres-Douglas theories is isomorphic to the unlinking of their 3d counterparts and that these symmetric quivers successfully capture the Schur indices of the original 4d theories.

SO(n) Affleck-Kennedy-Lieb-Tasaki states as conformal boundary states of integrable SU(n) spin chains

This paper constructs $\mathrm{SO}(n)$ -symmetric conformal boundary states in the $\mathrm{SU}(n)_1$ Wess-Zumino-Witten conformal field theory by embedding $\mathrm{Spin}(n)_2$ , identifies them as ground states of $\mathrm{SO}(n)$ Affleck-Kennedy-Lieb-Tasaki spin chains within the integrable $\mathrm{SU}(n)$ Uimin-Lai-Sutherland model, and analytically computes their boundary entropy using exact overlap formulas.

Particles before symmetry

This paper extends a geometry-first formulation of the Standard Model to spontaneous symmetry breaking and Yukawa couplings, demonstrating how these mechanisms can be explained through purely geometric terms that offer a more general and transparent account of charge quantization than traditional symmetry-based approaches.
