Topological Superconducting Phases in a Strained Altermagnet-Superconductor Heterostructure

Keita Yoshizawa, Ryo Okugawa, Takami Tohyama

We investigate topological superconductivity in a heterostructure consisting of a two-dimensional $s$-wave superconductor and a $d$-wave altermagnet with Rashba spin-orbit coupling…
