Parity effect and single-electron injection for Josephson-junction chains deep in the insulating state
K. Cedergren, S. Kafanov, J-L. Smirr +2
We have made a systematic investigation of charge transport in 1D chains of Josephson junctions where the characteristic Josephson energy is much less than the single-island Cooper…
High Q-factor Sapphire Whispering Gallery Mode Microwave Resonator at Single Photon Energies and milli-Kelvin Temperatures
Daniel L. Creedon, Yarema Reshitnyk, Warrick Farr +3
The microwave properties of a crystalline sapphire dielectric whispering gallery mode resonator have been measured at very low excitation strength (E/hf=1) and low temperatures (T…
Single Crystal Sapphire at milli-Kelvin Temperatures: Observation of Electromagnetically Induced Thermal Bistability in High Q-factor Whispering Gallery Modes
Daniel L. Creedon, Michael E. Tobar, Jean-Michel Le Floch +2
Resonance modes in single crystal sapphire (-AlO) exhibit extremely high electrical and mechanical Q-factors ( at 4K), which are important characteristics…
Photon generation in an electromagnetic cavity with a time-dependent boundary
C. M. Wilson, T. Duty, M. Sandberg +3
We report the observation of photon generation in a microwave cavity with a time-dependent boundary condition. Our system is a microfabricated quarter-wave coplanar waveguide cavit…
Is charge noise in single electron transistors and charge qubits caused by metallic grains?
S. Kafanov, H. Brenning, T. Duty +1
We report on measurements of low frequency noise in a single electron transistor from a few Hz up to 10 MHz. Measurements were done for different bias and gate voltages, which allo…
Observation of quantum capacitance in the Cooper-pair transistor
T. Duty, G. Johansson, K. Bladh +3
We have fabricated a Cooper-pair transistor (CPT) with parameters such that for appropriate voltage biases, the sub-gap charge transport takes place via slow tunneling of quasipart…
