Low-temperature AFM with a microwave cavity optomechanical transducer
Ermes Scarano, Elisabet K. Arvidsson, August K. Roos +4
We demonstrate AFM imaging with a microcantilever force transducer where an integrated superconducting microwave resonant circuit detects cantilever deflection using the principles…

Intrinsic Kerr amplification for microwave electromechanics
Ermes Scarano, Elisabet K. Arvidsson, August K. Roos +2
Electromechanical transduction gain of 21 dB is realized in a micro-cantilever resonant force sensor operated in the unresolved-sideband regime. Strain-dependent kinetic inductance…

Temperature dependence of microwave losses in lumped-element resonators made from superconducting nanowires with high kinetic inductance
Ermes Scarano, Elisabet K. Arvidsson, August K. Roos +2
We study the response of several microwave resonators made from superconducting NbTiN thin-film meandering nanowires with large kinetic inductance, having different circuit topolog…
