Current-induced cooling phenomenon in a two-dimensional electron gas under a magnetic field
Naomi Hirayama, Akira Endo, Kazuhiro Fujita +5
We investigate the spatial distribution of temperature induced by a dc current in a two-dimensional electron gas (2DEG) subjected to a perpendicular magnetic field. We numerically…
Quantum Nernst Effect in a Bismuth Single Crystal
Mari Matsuo, Akira Endo, Naomichi Hatano +3
We calculate the phonon-drag contribution to the transverse (Nernst) thermoelectric power in a bismuth single crystal subjected to a quantizing magnetic field. The calcula…
Fundamental relation between longitudinal and transverse conductivities in the quantum Hall system
Akira Endo, Naomichi Hatano, Hiroaki Nakamura +1
We investigate the relation between the diagonal () and off-diagonal () components of the conductivity tensor in the quantum Hall system. We calculate the conductiv…
Quantum Nernst effect in a bismuth single crystal
Mari Matsuo, Akira Endo, Naomichi Hatano +3
We report a theoretical calculation explaining the quantum Nernst effect observed experimentally in a bismuth single crystal. Generalizing the edge-current picture in two dimension…
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…
Gap-mediated magnetization of a pseudo-one-dimensional system with a spin-orbit interaction
Naomichi Hatano, Ryoen Shirasaki, Hiroaki Nakamura
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 intera…
