Leading UV Formula for Finite-Volume Vertex Operator Expectation Values in the Sine-Gordon Model from Kink NLIE
Arpad Hegedus, Apor Roth
We study the ultraviolet (UV) limit of finite-volume expectation values of vertex operators in the sine-Gordon model using the kink nonlinear integral equation (NLIE) description o…

Comparing the elliptic Ruijsenaars-Schneider model to the finite volume sine-Gordon theory
Zoltan Bajnok, Apor Roth
We compare the spectrum of the elliptic Ruijsenaars-Schneider model with the finite-size spectrum of the sine-Gordon model, highlighting both their similarities and differences. Ou…
