| Francisco(Paco) Guinea, Boston University 1pm, Serin 385 The effects of the interaction of simle 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. |
