Bethe Ansatz for Heisenberg XXX Model
arXiv:cond-mat/9509183
Abstract
We investigate Bethe Ansatz equations for the one-dimensional spin- Heisenberg XXX chain with a special interest in a finite system. Solutions for the two-particle sector are obtained. The ground state in antiferromagnetic case has been analytically studied through the logarithmic form of Bethe Ansatz equations.
