Topological charge pumping effect by the magnetization dynamics on the Surface of Three-Dimensional Topological Insulators
Hiroaki T. Ueda, Akihito Takeuchi, Gen Tatara +1
We discuss a current dynamics on the surface of a 3-dimensional topological insulator induced by magnetization precession of a ferromagnet attached. It is found that the magnetizat…
Charge pumping due to triplet vector chirality in ferromagnet/triplet superconductor junctions
Takehito Yokoyama
We investigate charge pumping in ferromagnet/triplet superconductor junctions where the magnetization of the ferromagnet is inhomogeneous and dynamical. It is shown that charge cur…
Electromagnetic spin polarization on the surface of topological insulator
Tetsuro Misawa, Takehito Yokoyama, Shuichi Murakami
We study the spin polarization of the electrons on the surface of topological insulators under a dc electric field or a circularly polarized light by using Keldysh Green's function…
Transverse Josephson effect due to spin-orbit coupling: Generation of transverse current without time-reversal symmetry breaking
Takehito Yokoyama
We investigate transverse Josephson current in superconductor/normal metal/superconductor junctions where the normal metal has Rashba type spin-orbit coupling. It is shown that tra…
Current induced magnetization reversal on the surface of a topological insulator
Takehito Yokoyama
We study dynamics of the magnetization coupled to the surface Dirac fermions of a three di- mensional topological insulator. By solving the Landau-Lifshitz-Gilbert equation in the…
Anisotropic supercurrent due to inhomogeneous magnetization in ferromagnet/superconductor junctions
Takehito Yokoyama, Yukio Tanaka, Shuichi Murakami
We investigate transverse charge and spin dc supercurrents in a ferromagnet coupled to a superconductor where the ferromagnet has inhomogeneous magnetic structure. These transverse…
Spin-current in generic hybrid structures due to interfacial spin-orbit scattering
J. Linder, T. Yokoyama
We demonstrate a general principle that hybrid structures of any sort inevitably will give rise to a pure spin-current flowing parallel to the interface region when a charge-curren…
Anomalous Meissner effect in NS junction with spin-active interface
Takehito Yokoyama, Yukio Tanaka, Naoto Nagaosa
We investigate Meissner effect in normal metal/superconductor junctions where the interface is spin-active. We find that orbital magnetic susceptibility of the normal metal shows h…
Topology of Andreev Bound States with Flat Dispersion
Masatoshi Sato, Yukio Tanaka, Keiji Yada +1
A theory of dispersionless Andreev bound states on surfaces of time-reversal invariant unconventional superconductors is presented. The generalized criterion for the dispersionless…
Anomalous magnetic transport in ferromagnetic graphene junctions
Takehito Yokoyama, Jacob Linder
We investigate magnetotransport in a ferromagnetic/normal/ferromagnetic graphene junction where a gate electrode is attached to the normal segment. It is shown that the charge cond…
Transverse magnetic heat transport on the topological surface
Takehito Yokoyama, Shuichi Murakami
We investigate transverse magnetic heat transport on the surface of a topological insulator on which a ferromagnet is attached. We present general expressions of the Nernst coeffic…
