Nonlinear Integral Equations for Thermodynamics of the U_{q}(\hat{sl(r+1)}) Perk-Schultz Model
Zengo Tsuboi, Minoru Takahashi
We propose a system of nonlinear integral equations (NLIE) which describes the thermodynamics of the U_{q}(\hat{sl(r+1)}) Perk-Schultz model. These NLIE correspond to a trigonometr…
TBA Equations of 1D Hubbard Model and High-Temperature Expansion
Minoru Takahashi, Masahiro Shiroishi
New numerical method to calculate thermodynmic Bethe ansatz equations is proposed based on Newton's method. Thermodynamic quantities of one-dimensional Hubbard model is numerically…
Equivalence of TBA and QTM
Minoru Takahashi, Masahiro Shiroishi, Andreas Klumper
The traditional thermodynamic Bethe ansatz (TBA) equations for the XXZ model at are derived within the quantum transfer matrix (QTM) method. This provides further eviden…
Asymptotic expansion of the ground state energy of half-filled Hubbard model
