Limitations in cooling electrons by normal metal - superconductor tunnel junctions
J. P. Pekola, T. T. Heikkila, A. M. Savin +3
We demonstrate both theoretically and experimentally two limiting factors in cooling electrons using biased tunnel junctions to extract heat from a normal metal into a superconduct…
Current-current correlations in hybrid superconducting and normal metal multiterminal structures
G. Bignon, M. Houzet, F. Pistolesi +1
We consider a hybrid system consisting of two normal metal leads weakly connected to a superconductor. Current-current correlations of the normal leads are studied in the tunneling…
One-shot quantum measurement using a hysteretic DC-SQUID
O. Buisson, F. Balestro, J. P. Pekola +1
We propose a single shot quantum measurement to determine the state of a Josephson charge quantum bit (qubit). The qubit is a Cooper pair box (CPB) and the measuring device is a tw…
Supercurrent in Long SFFS Junctions with Antiparallel Domain Configuration
Ya. M. Blanter, F. W. J. Hekking
We calculate the current-phase relation of a long Josephson junction consisting of two ferromagnetic domains with equal, but opposite magnetization , sandwiched between two supe…
Influence of thermal fluctuations on an underdamped Josephson tunnel junction
I. S. Beloborodov, F. W. J. Hekking, F. Pistolesi
Inspired by a recent experiment, we study the influence of thermal fluctuations on the - characteristics of a Josephson junction, coupled to a strongly resistive environment.…
Subgap noise of a superconductor-normal-metal tunnel interface
F. Pistolesi, G. Bignon, F. W. J. Hekking
It is well established that the subgap conductivity through a normal-metal-insulator-superconductor (NIS) tunnel junction is strongly affected by interference of electron waves sca…
Measurement of coherent charge transfer in an adiabatic Cooper pair pump
Rosario Fazio, F. W. J. Hekking, J. P. Pekola
We study adiabatic charge transfer in a superconducting Cooper pair pump, focusing on the influence of current measurement on coherence. We investigate the limit where the Josephso…
