 Suppression of quantum effects by metallic environments

(Institute of Materials Science (CSIC) Madrid, Spain)

Abstract:  The effects of the interaction of simple quantum systems with metallic environments are studied. The induced loss of coherence depends strongly on details of the interaction. A finite decoherence length at low energies can be defined for some environments, like the Caldeira-Leggett model, while not for others, like the dirty three dimensional electron gas. Applications to quantum dots and wires interacting with metallic gates are also presented.
