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…

Sensing force gradients with cavity optomechanics while evading backaction
Elisabet K. Arvidsson, Ermes Scarano, August K. Roos +2
We study force-gradient sensing with a coherently driven mechanical resonator and phase-sensitive detection of motion through the two-tone backaction evading measurement of cavity…
