Sr${}_2$(Ba${}_2$)VO${}_4$ under pressure -- an orbital switch and potential $d^1$ superconductor

R. Arita, A. Yamasaki, K. Held +2

We study Sr${}_2$(Ba${}_2$)VO${}_4$ under high pressure by means of the local density approximation + dynamical mean field theory method. While Sr${}_2$VO${}_4$ is a 1/6-filling three-band s…
