Surface density of states and topological edge states in non-centrosymmetric superconductors
Keiji Yada, Masatoshi Sato, Yukio Tanaka +1
We study Andreev bound state (ABS) and surface density of state (SDOS) of non-centrosymmetric superconductor where spin-singlet -wave pairing mixes with spin-triplet (or $f)…
Anomalous Andreev bound state in non-centrosymmetric superconductors
Yukio Tanaka, Yoshihiro Mizuno, Takehito Yokoyama +2
We study edge states of non-centrosymmetric superconductors where spin-singlet d-wave pairing mixes with spin-triplet p (or f)-wave one by spin-orbit coupling. For dxy-wave pairing…
Transport Properties in Ferromagnetic Josephson Junction between Triplet Superconductors
Yousef Rahnavard, Gholamreza Rashedi, Takehito Yokoyama
Charge and spin Josephson currents in a ballistic superconductor-ferromagnet-superconductor junction with spin-triplet pairing symmetry are studied using the quasiclassical Eilenbe…
Supercurrent-Induced Magnetization Dynamics
Jacob Linder, Takehito Yokoyama
We investigate supercurrent-induced magnetization dynamics in a Josephson junction with two misaligned ferromagnetic layers, and demonstrate a variety of effects by solving numeric…
Spin and Charge Currents in SNS Josephson Junction with f-wave Pairing Symmetry
Yousef Rahnavard, Gholamreza Rashedi, Takehito Yokoyama
We study transport properties and also local density of states in a clean superconductor-normal metal-superconductor Josephson junction with triplet f-wave superconductors based on…
Signature of odd-frequency pairing correlations induced by a magnetic interface
Jacob Linder, Asle Sudbø, Takehito Yokoyama +2
We investigate the mutual proximity effect in a normal metal contacted to a superconductor through a magnetic interface. Analytical and self-consistent numerical results are presen…
Interplay between Superconductivity and Ferromagnetism on a Topological Insulator
Jacob Linder, Yukio Tanaka, Takehito Yokoyama +2
We study theoretically proximity-induced superconductivity and ferromagnetism on the surface of a topological insulator. In particular, we investigate how the Andreev-bound states…
Dynamics of magnetization on the topological surface
Takehito Yokoyama, Jiadong Zang, Naoto Nagaosa
We investigate theoretically the dynamics of magnetization coupled to the surface Dirac fermions of a three dimensional topological insulator, by deriving the Landau-Lifshitz-Gilbe…
Gate-controlled one-dimensional channel on the topological surface
Takehito Yokoyama, Alexander V. Balatsky, Naoto Nagaosa
We investigate the formation of the one-dimensional channels on the topological surface under the gate electrode. The energy dispersion of these channels is almost linear in the mo…
