The entanglement of the XY spin chain in a random magnetic field
Masashi Fujinaga, Naomichi Hatano
We investigate the entanglement of the ferromagnetic XY model in a random magnetic field at zero temperature and in the uniform magnetic field at finite temperatures. We use the co…

Non-Abelian gauge field theory of the spin-orbit interaction and a perfect spin filter
Naomichi Hatano, Ryoen Shirasaki, Hiroaki Nakamura
We point out that the Rashba and Dresselhaus spin-orbit interactions in two dimensions can be regarded as a Yang-Mills non-Abelian gauge field. The physical field generated by the…
