Abstract

We examine a new two-band model which allows the coexistence of a spin liquid and conduction sea. Exchange coupling between the two fluids leads to Kondo-spin compensation of the spin liquid, generating bound states between the spin liquid and conduction electrons. When this occurs, the spin and charge degrees of freedom decouple, forming a superconductor of a novel kind.
