Nonlinear integral equations for the thermodynamics of the sl(4)-symmetric Uimin-Sutherland model

Publikováno v: J.Stat.Mech.0612:P12014,2006

We derive a finite set of nonlinear integral equations (NLIE) for the thermodynamics of the one-dimensional sl(4)-symmetric Uimin-Sutherland model. Our NLIE can be evaluated numerically for arbitrary finite temperature and chemical potentials. We rec

Nonlinear integral equations for thermodynamics of the sl(r+1) Uimin-Sutherland model

Autor: Tsuboi, Zengo

Publikováno v: J.Phys.A36:1493,2003

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 identical to the ones from the string hypothesis. Next we derive a new f

Fermionisation of the Spin-S Uimin-Lai-Sutherland Model: Generalisation of Supersymmetric t-J Model to Spin-S

Autor: Ambjorn, J., Karakhanyan, D., Mirumyan, M., Sedrakyan, A.

Publikováno v: Nucl.Phys. B599 (2001) 547-560

The spin-1 Uimin-Lai-Sutherland (ULS) isotropic chain model is expressed in terms of fermions and the equivalence of the fermionic representation to the supersymmetric t-J model is established directly at the level of Hamiltonians.The spin-S ULS mode

Anti-Symmetrically Fused Model and Non-Linear Integral Equations in the Three-State Uimin-Sutherland Model

Autor: Fujii, Akira, Kluemper, Andreas

We derive the non-linear integral equations determining the free energy of the three-state pure bosonic Uimin-Sutherland model. In order to find a complete set of auxiliary functions, the anti-symmetric fusion procedure is utilized. We solve the non-
