Query: Thermodynamic Bethe ansatz equation for osp(1|2) integrable spin chain   The thermodynamic Bethe ansatz is applied to a quantum integrable spin chain
associated with the Lie superalgebra osp(1|2). Using the string hypothesis, we
derive a set of infinite number of non-linear integral equations (thermodynamic
Bethe ansatz equation), which characterize the free energy. The low temperature
limit of the free energy is also discussed.
