Non-Abelian gauge field theory of the spin-orbit interaction and a perfect spin filter (2007)
Hatano, Naomichi, Shirasaki, Ryoen, Nakamura, Hiroaki
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 gauge field gives...
Gap-mediated magnetization of a pseudo-one-dimensional system with a spin-orbit interaction (2006)
Hatano, Naomichi, Shirasaki, Ryoen, Nakamura, Hiroaki
We argue that a pseudo-one-dimensional electron gas is magnetized when a voltage bias is applied with the Fermi level tuned to be in the energy gap generated by a spin-orbit interaction. The...

We report our recent predictions on the quantum Nernst effect, a novel thermomagnetic effect in the quantum Hall regime. We assume that, when the chemical potential is located between a pair of...
Nakamura, Hiroaki, Hatano, Naomichi, Shirasaki, Ryoen
It is theoretically predicted that the Nernst coefficient is strongly suppressed and the thermal conductance is quantized in the quantum Hall regime of the two-dimensional electron gas. The Nernst...

The hydrogen bond system is investigated using the electron-lattice model in which the interaction between the molecule and the hydrogen in the nearest neighbor one is considered as the Coulomb...
Isotope Effect on the Formation Energy of Soliton in t-Polyacetylene (1995)
The formation energy of a soliton was derived in the TLM model to be 2\Delta_{0}/\pi which is independent of the masses of the polymer atoms. We estimate effects of the electron-phonon coupling on...
Effects of the Lattice Discreteness on a Soliton in the Su-Schrieffer-Heeger Model (1995)
In this paper we analytically study the effects of the lattice discreteness on the electron band in the SSH model. We propose a modified version of the TLM model which is derived from the SSH model...
