Generic Weyl phase in the vortex state of quasi-two-dimensional chiral superconductors
Tomohiro Yoshida, Masafumi Udagawa
We study the collective behavior of Majorana modes in the vortex state of chiral -wave superconductors. Away from the isolated vortex limit, the zero-energy Majorana states comm…
Topological D+p-wave superconductivity in Rashba systems
Tomohiro Yoshida, Youichi Yanase
We show two-dimensional "strong" topological superconductivity in d-wave superconductors (SCs). Although the topological invariant of the bulk wave function cannot be defined in d_…
Excitation spectra and wave functions of quasiparticle bound states in bilayer Rashba superconductors
Yoichi Higashi, Yuki Nagai, Tomohiro Yoshida +2
We study the excitation spectra and the wave functions of quasiparticle bound states at a vortex and an edge in bilayer Rashba superconductors under a magnetic field. In particular…
Robust zero-energy bound states around a pair-density-wave vortex core in locally noncentrosymmetric superconductors
Yoichi Higashi, Yuki Nagai, Tomohiro Yoshida +2
We numerically investigate the electronic structures around a vortex core in a bilayer superconducting system, with s-wave pairing, Rashba spin-orbit coupling and Zeeman magnetic f…
Odd-parity superconductivity by competing spin-orbit coupling and orbital effect in artificial heterostructures
Tatsuya Watanabe, Tomohiro Yoshida, Youichi Yanase
We show that odd-parity superconductivity occurs in multilayer Rashba systems without requiring spin-triplet Cooper pairs. A pairing interaction in the spin-singlet channel stabili…
Topological Crystalline Superconductivity in Locally Non-centrosymmetric Multilayer Superconductors
Tomohiro Yoshida, Manfred Sigrist, Youichi Yanase
Topological crystalline superconductivity in the locally non-centrosymmetric multilayer superconductors (SCs) is proposed. We study the odd-parity pair-density wave (PDW) state ind…
Vortex Core Structure in Multilayered Rashba Superconductors
Yoichi Higashi, Yuki Nagai, Tomohiro Yoshida +1
We numerically study the electronic structure of a single vortex in two dimensional superconducting bilayer systems within the range of the mean-field theory. The lack of local inv…
Parity-Mixed Superconductivity in Locally Non-centrosymmetric System
Tomohiro Yoshida, Manfred Sigrist, Youichi Yanase
We study the parity-mixed superconductivity in locally non-centrosymmetric systems. In multilayer systems an inhomogeneous Rashba spin-orbit coupling is induced by the local violat…
Complex-Stripe Phases Induced by Staggered Rashba Spin-Orbit Coupling
Tomohiro Yoshida, Manfred Sigrist, Youichi Yanase
We study superconducting phases in a quasi-two-dimensional multilayer system without local inversion symmetry. Broken local inversion symmetry induces layer-dependent Rashba-type s…
Pair-density wave states through spin-orbit coupling in multilayer superconductors
Tomohiro Yoshida, Manfred Sigrist, Youichi Yanase
Spin singlet superconductors with quasi-two dimensional multilayer structure are studied in high magnetic fields. Specifically we concentrate on bi- and tri-layer systems whose lay…
Rotating Fulde-Ferrell-Larkin-Ovchinnikov state in cold Fermi gases
Tomohiro Yoshida, Youichi Yanase
We study an effect of rotation on the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state of two component Fermi superfluid gases in a toroidal trap. We investigate a stability of the FF…
