摘要: Two implicit periodic structures in the solution of sinh-Gordon thermodynamic Bethe ansatz (TBA) equation are considered. The analytic structure as a function complex θ is studied to some extent both analytically and numerically. results hint at how CFT integrable can be relevant staircase models. More motivations figured out for subsequent studies massless (i.e. Liouville) TBA equation.
