Parametric amplification with weak-link nonlinearity in superconducting microresonators
Erik A. Tholen, Adem Ergul, Kai Stannigel +2
Nonlinear kinetic inductance in a high Q superconducting coplanar waveguide microresonator can cause a bifurcation of the resonance curve. Near the critical pumping power and frequ…
Nonlinearities and Parametric Amplification in Superconducting Coplanar Waveguide Resonators
Erik A. Tholen, Adem Ergul, Evelyn M. Doherty +3
Experimental investigations of the nonlinear properties of superconducting niobium coplanar waveguide resonators are reported. The nonlinearity due to a current dependent kinetic i…
Pulse and hold strategy for switching current measurements
Jochen Walter, Erik Tholen, Joachim Sjostrand +1
We investigate by theory and experiment, the Josephson junction switching current detector in an environment with frequency dependent damping. Analysis of the circuit's phase space…
Phase space topology of a switching current detector
J. Sjostrand, J. Walter, E. Tholen +3
We examine in theory and by numerical simulation, the dynamic process of switching from a zero voltage to a finite voltage state in a Josephson junction circuit. The theoretical mo…
