Field-induced metal-insulator transition and switching phenomenon in correlated insulators
Naoyuki Sugimoto, Shigeki Onoda, Naoto Nagaosa
We study the nonequilibrium switching phenomenon associated with the metal-insulator transition under electric field E in correlated insulator by a gauge-covariant Keldysh formalis…
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…
Theory of Non-Equilibirum States Driven by Constant Electromagnetic Fields: Non-Commutative Quantum Mechanics in the Keldysh Formalism
Shigeki Onoda, Naoyuki Sugimoto, Naoto Nagaosa
We develop a general theory of non-equilibrium states based on the Keldysh formalism, in particular, for charged-particle systems under static uniform electromagnetic fields. The D…
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…
