Entanglement and the Kondo effect in double quantum dots
arXiv:cond-mat/0701363 · doi:10.1140/epjb/e2008-00089-9
Abstract
We investigate entanglement between electrons in serially coupled double quantum dots attached to non interacting leads. In addition to local repulsion we consider the influence of capacitive inter-dot interaction. We show how the competition between extended Kondo and local singlet phases determines the ground state and thereby the entanglement.
