Spin response of impurities in a quantum corral
2014
In this work we investigate the dependence of spin observables, like the total spin alignment and the spin squeezing factor, for electrons confined inside an elliptic quantum corral and interacting with a pair of impurities located on the semi-major axis of the ellipse. The results suggest that such a system exhibits some of the characteristic features of a qubit, concerning the persistence of the orientation and squeezing of a component of the total spin.
