Pressure-Induced Superconducting-like Transition in the $d$-wave Altermagnet Candidate CsV${}_2$Se${}_2$O

Yuanzhe Li, Yilin Han, Liu Yang +29

Altermagnetism generates exchange-type spin splitting without net magnetization and, in its $d$-wave form, resembles the angular symmetry of unconventional $d$-wave superco…
