Ab initio determination of an extended Heisenberg Hamiltonian in CuO2 layers
Carmen J. Calzado, Jean-Paul Malrieu
Accurate ab initio calculations on embedded Cu_4O_{12} square clusters, fragments of the La_2CuO_4 lattice, confirm a value of the nearest neighbor antiferromagnetic coupling (J=12…

Proposal of an extended t-J Hamiltonian for high-Tc cuprates from ab initio calculations on embedded clusters
Carmen J. Calzado, Jean-Paul Malrieu
A series of accurate ab initio calculations on Cu_pO-q finite clusters, properly embedded on the Madelung potential of the infinite lattice, have been performed in order to determi…
