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…
