Inelastic scattering of microwave radiation in the dynamical Coulomb blockade
Juha Leppäkangas, Michael Marthaler
We study scattering of propagating microwave fields by a DC-voltage biased Josephson junction. At sub-gap voltages, a small Josephson junction works merely as a non-linear boundary…
Decoherence spectroscopy with individual two-level tunneling defects
Jürgen Lisenfeld, Alexander Bilmes, Shlomi Matityahu +7
Recent progress with microfabricated quantum devices has revealed that an ubiquitous source of noise originates in tunneling material defects that give rise to a sparse bath of par…
The parity effect in Josephson junction arrays
Jared H. Cole, Andreas Heimes, Timothy Duty +1
We study the parity effect and transport due to quasiparticles in circuits comprised of many superconducting islands. We develop a general approach and show that it is equivalent t…
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…
Thermally activated conductance in arrays of small Josephson junctions
J. Zimmer, N. Vogt, A. Fiebig +7
We present measurements of the temperature-dependent conductance for series arrays of small-capacitance SQUIDs. At low bias voltages, the arrays exhibit a strong Coulomb blockade,…
Circuit-QED analogue of a single-atom injection maser: Lasing, trapping states and multistability
M. Marthaler, J. Leppäkangas, J. H. Cole
We study a superconducting single-electron transistor (SSET) which is coupled to a LC-oscillator via the phase difference across one of the Josephson junctions. This leads to a str…
