Nonlinear integral equations for thermodynamics of the sl(r+1) Uimin-Sutherland model
Zengo Tsuboi
We derive traditional thermodynamic Bethe ansatz (TBA) equations for the sl(r+1) Uimin-Sutherland model from the T-system of the quantum transfer matrix. These TBA equations are id…

Integral equations for thermodynamics of the osp(1|2s) integrable spin chain
Zengo Tsuboi
We propose a system of nonlinear integral equations (NLIE), which gives the free energy of the osp(1|2s) integrable spin chain at finite temperatures. In contrast with usual thermo…
