Thermodynamics in the sine-Gordon model: the NLIE approach
In this paper we derive Klümper-Batchelor-Pearce-Destri-de Vega type nonlinear integral equations for describing the thermodynamics in the sine-Gordon model, when a chemical potential coupled to the topological charge is also present in the theory. The equations are valid at any value of the couplin...
