Flat-band Majorana bound states in topological Josephson junctions
Daisuke Oshima, Satoshi Ikegaya, Andreas P. Schnyder +1
Nodal topological superconductors characterized by -wave pairing symmetry host flat-band Majorana bound states causing drastic anomalies in low-energy electromagnetic response…
Spin Hall conductivity in topological Dirac semimetals
Katsuhsia Taguchi, Daisuke Oshima, Yusuke Yamaguchi +3
We theoretically investigate the spin Hall conductivity (SHC) in topological Dirac semimetals (TDSMs) whose Dirac points are protected by rotational symmetry. On the basis of a gen…
Unconventional gate voltage dependence of the charge conductance caused by spin-splitting Fermi surface by Rashba-type spin-orbit coupling
D. Oshima, K. Taguchi, Y. Tanaka
We calculate the gate voltage (Vg) dependence of charge conductance in a normal metal (NM)/two dimensional electron gas (2DEG) junction, where Rashba spin-orbit coupling and ferrom…
Spin-Dependent Conductance in a Junction with Dresselhaus Spin-Orbit Coupling
Daisuke Oshima, Katsuhisa Taguchi, Yukio Tanaka
We studied spin-dependent conductance in a normal metal (NM)/NM junction with Dresselhaus spin-orbit coupling (DSOC) and magnetization. As a reference, we also studied the spin-dep…
Tunneling conductance in two-dimensional junctions between a normal metal and a ferromagnetic Rashba metal
Daisuke Oshima, Katsuhisa Taguchi, Yukio Tanaka
We have studied charge transport in ferromagnetic Rashba metal (FRM), where both Rashba type spin-orbit coupling (RSOC) and exchange coupling coexist. It has nontrivial metallic st…
