Theory of magnetic excitations in multilayer nickelate superconductor La${}_3$Ni${}_2$O${}_7$

Steffen Bötzel, Frank Lechermann, Jannik Gondolf +1

Motivated by the recent reports of high-$T_c$ superconductivity in La${}_3$Ni${}_2$O${}_7$ under pressure, we analyzed theoretically the magnetic excitations in the normal and the superc…
