An ab-initio evaluation of the local effective interactions in the $N a_{x} Co O_{2}$ familly

Sylvain Landron, Soret Julien, Marie-Bernadette Lepetit

We used quantum chemical ab initio methods to determine the effective parameters of Hubbard and $t - J$ models for the $N a_{x} Co O_{2}$ compounds (x=0 and 0.5). As for the supercond…

The crucial importance of the $t_{2 g}$ -- $e_{g}$ hybridization in transition metal oxides

Sylvain Landron, Marie-Bernadette Lepetit

We studied the influence of the trigonal distortion of the regular octahedron along the (111) direction, found in the $Co O_{2}$ layers. Under such a distortion the $t_{2 g}$ orbit…

An ab-initio evaluation of the local effective interactions in the superconducting compound $Na_0.35 CoO_2 - 1.3H_2O$

Sylvain Landron, Marie-Bernadette Lepetit

We used ab-initio quantum chemical methods, treating explicitly the strong correlation effects within the cobalt 3d shell, as well as the screening effects on the effective integra…
