Density functional electronic spectrum of the $Cu{O}_{-6}^{-10}$ cluster and possible local Jahn-Teller distorsions in the La-Ba-Cu-O superconductor

J. R. Soto, J. J. Castro, E. Yépez +1

We present a density functional theory (DFT) calculation in the generalized gradient approximation to study the possibility for the existence of Jahn-Teller (JT) or pseudo Jahn-Tel…
