✦ Synopsis
A study of electron correlation effects on the properties of LaxSrt.xTiO3 is presented using a single band repulsive Hubbard. model and employing Gutzwiller approximation. A possibility of inducing superconductivity in this material is suggested.

Electrical transport, both resistivity and thermopower, and heat capacity data are reported for two systems of cation vacancy-doped titanate perovskites, Nd 1؊x TiO 3 and Sm 1؊x TiO 3 . In the former case the range of x is from 0.33 to 0.00 and for the latter from 0.17 to 0.00. Thus, the nominal car
The proposed AxC60 model involves strong Hubbard energy of alkali electrons in the narrow molecular LUMO band (lowest unoccupied molecular orbital) of C6o. By invoking a kinematical high-T c mechanism, we obtained an expression for Tc(X) and found the superconductivity gap A o which satisfies the in
