Hall Shift Current and Nonlinear Anomalous Hall Effect in Gapped Dirac Fermion Systems
Toshihito Osada
We discuss a new mechanism for the nonlinear anomalous Hall effect in tilted two-dimensional gapped Dirac fermion systems. This mechanism originates from a side-jump displacement a…

Wannier Center Analysis on Possible Three-Dimensional Topological Phases in α-Type Layered Organic Conductors
Toshihito Osada
Topological features of possible three-dimensional (3D) states in α-type layered organic conductors are investigated within a unified framework based on Wannier charge centers (WC…

Three-Dimensional Topological Semimetal/Insulator States in α-Type Organic Conductors with Interlayer Spin-Orbit Interaction
Toshihito Osada
We have studied the tight-binding model for the α-type layered organic conductors, α-(ET)2I3 and α-(BETS)2I3, with a uniform interlayer coupling accompanied by spin-orbit intera…
