High- superconductivity by phase cloning
arXiv:hep-th/0701245
Abstract
We consider a BCS-type model in the spin formalism and argue that the structure of the interaction provides a mechanism for control over directions of the spin $\vect S$ other than , which is being controlled via the conventional chemical potential. We also find the conditions for the appearance of a high- superconducting phase.
