Paramagnetic instability of small topological superconductors
Shu-Ichiro Suzuki, Yasuhiro Asano
Although the diamagnetism is of the essence in the superconducting phenomena, small enough topological (or unconventional) superconductors are paramagnetic. By solving the quasicla…
Quantum Landau Spin Hall Insulator
Tetsuro Habe, Yasuhiro Asano
We study theoretically the two-dimensional topological electric state in a single band semiconductor with strong spin-orbit interactions under harmonic scalar electrostatic potenti…
Three-dimensional symmetry breaking topological matters
Tetsuro Habe, Yasuhiro Asano
We discuss topological electronic states described by the Dirac Hamiltonian plus an additional one in three-dimension. When the additional Hamiltonian is an element of an Abelian g…
Charge and spin supercurrents in triplet superconductor--ferromagnet--singlet superconductor Josephson junctions
P. M. R. Brydon, Wei Chen, Yasuhiro Asano +1
We study the Josephson effect in a triplet superconductor--ferromagnet--singlet superconductor junction. We show that the interaction of tunneling Cooper pairs with the interface m…
Robustness of Spin-Triplet Pairing and Singlet-Triplet Pairing Crossover in Superconductor/Ferromagnet Hybrids
Shiro Kawabata, Yasuhiro Asano, Yukio Tanaka +1
We have investigated the proximity effect in superconductor/ferromagnet junctions in a systematic manner to discuss the relationship between the zero-energy peak (ZEP) of the local…
Robustness of Gapless Interface State in a Junction of Two Topological Insulators
Tetsuro Habe, Yasuhiro Asano
We theoretically study subgap states appearing at the interface between two three-dimensional topological insulators which have different configurations in the spin-orbit interacti…
