TBA equations for $SU(r+1)$ quantum Seiberg-Witten curve: higher-order Mathieu equation

Feiyu Peng, Hongfei Shu · 2026

We develop the ODE/IM correspondence for the higher-order Mathieu equation arising from the quantum Seiberg-Witten curve of the pure $SU(r+1)$ ${\cal N}=2$ supersymmetric Yang-Mills theory. From the s…

A perturbative Liouville prescription for the celestial three-gluon amplitude

Grzegorz Biskowski, Franco Ferrari, Marcin R. Piatek, Artur R. Pietrykowski · 2026

We study the celestial three-gluon amplitude in a dilaton background through the Mellin-Liouville formulation proposed by Stieberger, Taylor and Zhu (STZ). The original map contains an ambiguity in th…

The quantum group structure of long-range integrable deformations

Koen Schouten, Marius de Leeuw · 2026

Quantum integrable spin chains are known to possess a large family of long-range deformations generated by the local, boost and bilocal operators. Although these deformations are well-understood on th…

Scalene Yang-Baxter maps and Lax triples

S. Konstantinou-Rizos, T. Kouloukas · 2026

We study a generalisation of the set-theoretic Yang-Baxter equation and investigate the connection between its solutions and matrix refactorisation problems. We refer to such solutions as scalene Yang…

Integrable Deformations of the Breitenlohner-Maison Model from 4d Chern-Simons Theory

Meer Ashwinkumar, Matthias Blau · 2026

We derive integrable deformations of the 2d Breitenlohner-Maison (BM) sigma model that describes the stationary, axisymmetric sector of 4d general relativity, as well as higher-rank generalisations th…

Quarter-indices for basic ortho-symplectic corners

Yasuyuki Hatsuda, Tadashi Okazaki · 2026

We study supersymmetric quarter-indices for corner configurations in 4d $\mathcal{N}=4$ super Yang-Mills theory with orthogonal and symplectic gauge groups. For the basic Y-junctions, we obtain exact …

Metrics on triangulated categories and restrictions of (co)-$t$-structures

Wei Hu, Ziheng Liu · 2026

This paper explores the restriction behavior of silting-induced $t$-structures and co-$t$-structures on triangulated categories endowed with metrics. For compactly generated triangulated categories ad…

Quantum Flat Connections, KZ equations, and Integrability

Sibasish Banerjee, Babak Haghighat, Anouchah Latifi · 2026

N=2 supyersymmetric Yang-Mills theories are described in terms of a Hitchin system over a Riemann surface C. Focusing on strongly coupled Argyres-Douglas theories, we show that the corresponding flat …

Cartan Fluxes in $SU(3)$ Lattice Gauge Theory

Tereza Mendes, Luis E. Oxman, Gustavo M. Simoes, Rafael C.S. Tonhon · 2026

We propose and analyze a new method of detecting center vortices and monopoles in lattice Yang-Mills theory. This procedure is sensitive to the intrinsic degeneracy of the center charges, which play a…
