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…
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…
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…
Quantum Nernst Effect
Hiroaki Nakamura, Naomichi Hatano, Ryoen Shirasaki
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 betw…
Quantum Nernst Effect
Hiroaki Nakamura, Naomichi Hatano, Ryoen Shirasaki
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…
