Electron and phonon Cooling in a Superconductor - Normal Metal - Superconductor Tunnel Junction
Sukumar Rajauria, P. S. Luo, T. Fournier +3
We present evidence for the cooling of normal metal phonons by electron tunneling in a Superconductor - Normal metal - Superconductor tunnel junction. The normal metal electron tem…
Coulomb blockade of Cooper pair tunneling and parity effects in the Cooper pair transistor
S. Corlevi, W. Guichard, F. W. J. Hekking +1
We have measured the Cooper Pair Transistor (CPT) in a tunable electromagnetic environment consisting of four one-dimensional SQUID arrays. The transport properties of the CPT in t…
Frequency-dependent current correlation functions from scattering theory
J. Salo, F. W. J. Hekking, J. P. Pekola
We present a general formalism based on scattering theory to calculate quantum correlation functions involving several time-dependent current operators. A key ingredient is the cau…
Measurement scheme of the Berry phase in superconducting circuits
Mikko Mottonen, Jukka P. Pekola, Juha J. Vartiainen +2
We present a measurement scheme for observing the Berry phase in a flux assisted Cooper pair pump - the Cooper pair sluice. In contrast to the recent experiments, in which the slui…
Qubits as devices to detect the third moment of current fluctuations
Valentina Brosco, Rosario Fazio, F. W. J. Hekking +1
Under appropriate conditions controllable two-level systems can be used to detect the third moment of current fluctuations. We derive a Master Equation for a quantum system coupled…
