A direct calculation of the free energy from the Bethe ansatz equation for the Heisenberg model
Go Kato, Miki Wadati
Thermodynamics of the XXX Heisenberg model is studied. The trace of the Boltzmann weight with respect to the Hilbert space is taken in the thermodynamic limit with the number of up…
Direct Calculation of Thermodynamic Quantities for Heisenberg Model
Go Kato, Miki Wadati
The XXX Heisenberg model is studied at finite temperature. The free energy is derived without recourse to Thermal Bethe Ansatz method and Quantum Transfer Matrix method. The result…
Graphical representation of the partition function for a 1-D delta-function Bose gas
Go Kato, Miki Wadati
One-dimensional repulsive delta-function bose system is studied. By only using the Bethe ansatz equation, n-particle partition functions are exactly calculated. From this expressio…
Partition Function for a 1-D delta-function Bose Gas
Go Kato, Miki Wadati
The N-particle partition function of a one-dimensional -function bose gas is calculated explicitly using only the periodic boundary condition (the Bethe ansatz equation). The N-…
