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…
Adiabatic Green's function technique and the transient behavior in time-dependent fermion-boson coupled models
Yun-Tak Oh, Yoichi Higashi, Ching-Kit Chan +1
The Lang-Firsov Hamiltonian, a well-known solvable model of interacting fermion-boson system with sideband features in the fermion spectral weight, is generalized to have the time-…
