Topological superconductivity in helical crystals
Soma Yoshida, Keiji Yada, Yukio Tanaka +1
We study superconductivity and surface Andreev bound states in helical crystals. We consider the interlayer pairings along the helical hopping and investigate the surface local den…
Vortex supercurrent inversion by frequency-symmetry conversion of Cooper pairs
Soma Yoshida, Shu-Ichiro Suzuki, Yukio Tanaka
We theoretically demonstrate that the vortex supercurrent can be reversed by odd-frequency Cooper pairs accompanied by surface Andreev bound states. The surface of a three-dimensio…
Theory of pair density wave on a quasi-one-dimensional lattice in the Hubbard model
Soma Yoshida, Keiji Yada, Yukio Tanaka
In this study, we examine the superconducting instability of a quasi-one-dimensional lattice in the Hubbard model based on the random-phase approximation (RPA) and the fluctuation…
