Pressure Induced Topological Superconductivity in the Spin-Orbit Mott Insulator GaTa4Se8

Moon Jip Park, GiBaik Sim, Min Yong Jeong +3

Lacunar spinel GaTa${}_4$Se${}_8$ is a unique example of spin-orbit coupled Mott insulator described by molecular $j_{\text{eff}}=3/2$ states. It becomes superconducting at T${}_c$=5…
