Landau-Zener tunneling problem for Bloch states
Ryuji Takahashi, Naoyuki Sugimoto
We study the Landau-Zener tunneling problem for particles bound in periodic lattice insulators. To this end, we construct the path integral based on the Bloch and Wannier functions…
Current control of systems with a Peierls distortion by magnetic field
Ryuji Takahashi, Naoyuki Sugimoto
We study the tunneling phenomenon of a ladder system with a Peierls distortion in a magnetic flux, and the response of electrons the insulator is investigated when the tunneling cu…
Semiclassical Lattice effects on interband tunneling of a two-state system
Ryuji Takahashi, Naoyuki Sugimoto
Previously, we have shown that the transition probability of the Landau-Zener problem in periodic lattice systems becomes large by taking into account the nonlinearity of the energ…
Quantum transport theory of anomalous electric, thermoelectric, and thermal Hall effects in ferromagnets
Shigeki Onoda, Naoyuki Sugimoto, Naoto Nagaosa
The mechanism of the anomalous Hall transport phenomena, if it is of the intrinsic or extrinsic origin, has been controversial. We present a unified theory of them for ferromagneti…
Intrinsic vs. extrinsic anomalous Hall effect in ferromagnets
Shigeki Onoda, Naoyuki Sugimoto, Naoto Nagaosa
A unified theory of the anomalous Hall effect (AHE) is presented for multi-band ferromagnetic metallic systems with dilute impurities. In the clean limit, the AHE is mostly due to…
Spin Hall effect of conserved current: Conditions for a nonzero spin Hall current
Naoyuki Sugimoto, Shigeki Onoda, Shuichi Murakami +1
We study the spin Hall effect taking into account the impurity scattering effect as general as possible with the focus on the definition of the spin current. The conserved bulk spi…
