Vortices coupled to a granular aluminum stripline resonator
ORAL
Abstract
Since mobile vortices in superconductors typically add dissipation, understanding and controlling their dynamics can help improve the performance of superconducting quantum devices. Vortices can be introduced either by field cooling a superconductor or, at base temperature, by exceeding a threshold magnetic field perpendicular to the thin film of the device. We present the effects of vortices in stripline resonators made from granular aluminum.
