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

Feiyu Peng, Hongfei Shu ยท 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 sโ€ฆ

Torus one-point functions in critical loop models

Paul Roux, Sylvain Ribault, Jesper Lykke Jacobsen ยท 2026

We show that in critical loop models, torus 1-point functions can be expressed in terms of sphere 4-point functions at a different central charge. Unlike in the Moore--Seiberg formalism, crossing symmโ€ฆ

Accelerating quantum Gibbs sampling without quantum walks

Jiaqi Leng, Jiaqing Jiang, Lin Lin ยท 2026

Szegedy's quantum walk gives a generic quadratic speedup for reversible classical Markov chains, but extending this mechanism to quantum Gibbs sampling has remained challenging beyond special cases. Wโ€ฆ
