A self-calibrating superconducting pair-breaking detector
E. T. Mannila, V. F. Maisi, J. P. Pekola
We propose and experimentally demonstrate a self-calibrating detector of Cooper pair depairing in a superconductor based on a mesoscopic superconducting island coupled to normal me…
A superconductor free of quasiparticles for seconds
E. T. Mannila, P. Samuelsson, S. Simbierowicz +6
Superconducting devices, based on the Cooper pairing of electrons, play an important role in existing and emergent technologies, ranging from radiation detectors to quantum compute…
Interplay of charge and vorticity quantization in superconducting Coulomb blockaded island
I. M. Khaymovich, V. F. Maisi, J. P. Pekola +1
The angular momentum or vorticity of Cooper pairs is shown to affect strongly the charge transfer through a small superconducting (S) island of a single electron transistor. This i…
Tunneling and Relaxation of Single Quasiparticles in a Normal-Superconductor-Normal Single Electron Transistor
Andreas Heimes, Ville F. Maisi, Dmitri S. Golubev +3
We investigate the properties of a hybrid single electron transistor, involving a small superconducting island sandwiched between normal metal leads, which is driven by dc plus ac…
Single quasiparticle excitation dynamics on a superconducting island
V. F. Maisi, S. V. Lotkhov, A. Kemppinen +3
We investigate single quasiparticle excitation dynamics on a small superconducting aluminum island connected to normal metallic leads by tunnel junctions. We find the island to be…
Probing quasiparticle excitations in a hybrid single electron transistor
H. S. Knowles, V. F. Maisi, J. P. Pekola
We investigate the behavior of quasiparticles in a hybrid electron turnstile with the aim of improving its performance as a metrological current source. The device is used to direc…
Vanishing quasiparticle density in a hybrid Al/Cu/Al single-electron transistor
O. -P. Saira, A. Kemppinen, V. F. Maisi +1
The achievable fidelity of many nanoelectronic devices based on superconducting aluminum is limited by either the density of residual nonequilibrium quasiparticles n_qp or the dens…
Photon assisted tunneling as an origin of the Dynes density of states
J. P. Pekola, V. F. Maisi, S. Kafanov +6
We show that the effect of a high-temperature environment in current transport through a normal metal-insulator-superconductor tunnel junction can be described by an effective dens…
