Probing dynamics of an electron-spin ensemble via a superconducting resonator
V. Ranjan, G. de Lange, R. Schutjens +7
We study spin relaxation and diffusion in an electron-spin ensemble of nitrogen impurities in diamond at low temperature (0.25-1.2 K) and polarizing magnetic field (80-300 mT). Mea…
Microwave-induced nonequilibrium temperature in a suspended carbon nanotube
H. L. Hortensius, A. Ozturk, P. Zeng +2
Antenna-coupled suspended single carbon nanotubes exposed to 108 GHz microwave radiation are shown to be selectively heated with respect to their metal contacts. This leads to an i…
Strongly disordered TiN and NbTiN s-wave superconductors probed by microwave electrodynamics
E. F. C. Driessen, P. C. J. J. Coumou, R. R. Tromp +2
We probe the effects of strong disorder (2.4 < kFl < 8.6) on superconductivity in thin films of niobium titanium nitride and titanium nitride by measuring the microwave electrodyna…
Microwave-induced excess quasiparticles in superconducting resonators measured through correlated conductivity fluctuations
P. J. de Visser, J. J. A. Baselmans, S. J. C. Yates +3
We have measured the number of quasiparticles and their lifetime in aluminium superconducting microwave resonators. The number of excess quasiparticles below 160 mK decreases from…
Critical-Current Reduction in Thin Superconducting Wires Due to Current Crowding
H. L. Hortensius, E. F. C. Driessen, T. M. Klapwijk +2
We demonstrate experimentally that the critical current in superconducting NbTiN wires is dependent on their geometrical shape, due to current-crowding effects. Geometric patterns…
Evanescent states and non-equilibrium in driven superconducting nanowires
N. Vercruyssen, T. G. A. Verhagen, M. G. Flokstra +2
We study the non linear response of current-transport in a superconducting diffusive nanowire between normal reservoirs. We demonstrate theoretically and experimentally the existen…
