Charge ordering in Ni${}^{1+}$/Ni${}^{2+}$ nickelates: La${}_4$Ni${}_3$O${}_8$ and La${}_3$Ni${}_2$O${}_6$

A. S. Botana, V. Pardo, W. E. Pickett +1

Ab initio calculations have been performed to unravel the origin of the recently found superlattice peaks in the trilayer nickelate La${}_4$Ni${}_3$O${}_8$. These peaks arise from static…
