Numerical Study of the One-Dimensional Spin-Orbit Coupled System with SU(2)SU(2) Symmetry
Yasufumi Yamashita, Naokazu Shibata, Kazuo Ueda
We numerically study the SU(2)SU(2) symmetric spin-orbit coupled model as a lower symmetric generalization of the SU(4) exchange model. On the symmetric line with respect…

Crossover Phenomena in the One-Dimensional SU(4) Spin-Orbit Model under Magnetic Fields
Yasufumi Yamashita, Naokazu Shibata, Kazuo Ueda
We study the one-dimensional SU(4) exchange model under magnetic fields, which is the simplest effective Hamiltonian in order to investigate the quantum fluctuations concerned with…
