Pressure and strain effects on the $\text{ab initio}$ $GW$ electronic structure of La${}_3$Ni${}_2$O${}_7$

Jean-Baptiste de Vaulx, Quintin N. Meier, Pierre Toulemonde +2

The recent discovery of superconductivity in La${}_3$Ni${}_2$O${}_7$ at a critical temperature above 80~K points to a non-conventional pairing mechanism in nickelates as in cuprates, pos…
