Resistance measurements in CuRh2S4 under quasihydrostatic pressure are performed, and a pressure-induced superconductor-insulator transition is found, where superconductivity disappears abruptly at a critical pressure P(SI) between 5.0 and 5.6 GPa.

The periodic Anderson model can be studied in the limit U=∞ by employing the Hubbard X operators to project out the unwanted states. We had already studied this problem by employing the cumulant

We present a mean-field study of superconductivity in a generalized N-channel cubic Anderson lattice at U=\infty taking into account the effect of a nearest-neighbor attraction J. The condition
