12 Oct 1999 | | Subject: | Mesoscopic Systems and Quantum Hall Effect; Superconductivity | cond-mat.mes-hall cond-mat.supr-con | | Affiliation: | Institut fuer Theoretische Festkoerperphysik, Universitaet Karlsruhe, Germany), and Gergely T. Zimanyi (Department of Physics, UC Davis, U.S.A | | Abstract: | We study a superconducting single-charge transistor, where the coherence of Cooper pair tunneling is destroyed by the coupling to a tunable dissipative environment. Sequential tunneling and cotunneling processes are analyzed to construct the shape of the conductance peaks and their dependence on the dissipation and temperature. Unexpected features are found due to a cross-over between two distinct regimes, one `environment-assisted’ the other `environment-dominated’. Several of the predictions have been confirmed by recent experiments. The model and results apply also to the dynamics of Josephson junction quantum bits on a conducting ground plane, thus explaining the influence of dissipation on the coherence. | | Source: | arXiv, cond-mat/9910179 | | Other source: | [GID 438370] pmid11580615 | | Services: | Forum | Review | PDF | Favorites | |
