Abstract

We discuss an integrable model of string on AdS$_3$xS$^3$xT$^4$ in a thermodynamical bath. We show that scattering of the excitations above equilibrium states has some novel features. Thermodynamics points to interesting deformation of the original model for which we discuss finite size effect through mirror TBA equations.
