Thermomagnetic Power and Figure of Merit for Spin-1/2 Heisenberg Chain
Shunsuke Furukawa, Dai Ikeda, Kazumitsu Sakai
Transport properties in the presence of magnetic fields are numerically studied for the spin-1/2 Heisenberg XXZ chain. The breakdown of the spin-reversal symmetry due to the magnet…

Exact Analysis of ESR Shift in the Spin-1/2 Heisenberg Antiferromagnetic Chain
Y. Maeda, K. Sakai, M. Oshikawa
A systematic perturbation theory is developed for the ESR shift and is applied to the spin-1/2 Heisenberg chain. Using the Bethe ansatz technique, we exactly analyze the resonance…
