Finite Temperature Excitations of the XYZ Spin Chain

概要
- 論文の詳細を見る
A procedure is presented to obtain finite temperature excitations of the XYZ spin chain. Numerical results agree with the analytic expressions derived by Johnson, Krinsky and McCoy at T=0. The numerical results also agree with those of the Heisenberg-Ising ring by Johnson at T≠0. Sample dispersion curves are illustrated for the"scaling region", which is expected to have an equivalence to the massive Thirring model. Temperature dependences are calculated for some types of elementary excitations.
