Electronic structure of Ruddlesden-Popper nickelates: strain to mimic the effects pressure

Yi-Feng Zhao, Antia S. Botana

Signatures of superconductivity under pressure have recently been reported in the bilayer La${}_3$Ni${}_2$O${}_7$ and trilayer La${}_4$Ni${}_3$O${}_{10}$ Ruddlesden-Popper (RP) nickelates with…
