Decoherence of cold atomic gases in magnetic micro-traps
C. Schroll, W. Belzig, C. Bruder
We derive a model to describe decoherence of atomic clouds in atom-chip traps taking the excited states of the trapping potential into account. We use this model to investigate dec…
Influence of dephasing on shot noise in a Mach-Zehnder interferometer: Dephasing terminal model
Florian Marquardt, C. Bruder
This paper has been retracted. The authors have discovered a possible problem in applications of the dephasing terminal approach to shot noise calculations in interference situatio…
Multiple Andreev Reflections in a Carbon Nanotube Quantum Dot
M. R. Buitelaar, W. Belzig, T. Nussbaumer +3
We report resonant multiple Andreev relections in a multiwall carbon nanotube quantum dot coupled to superconducting leads. The position and magnitude of the subharmonic gap struct…
Variable electrostatic transformer: controllable coupling of two charge qubits
D. V. Averin, C. Bruder
We propose and investigate a novel method for the controlled coupling of two Josephson charge qubits by means of a variable electrostatic transformer. The value of the coupling cap…
