Thermometry with Optomechanical Cavities



Thomas P. Purdy, Karen E. Grutter, Kartik Srinivasan, Nikolai Klimov, Zeeshan Ahmed, Jacob Taylor


Thermally-driven motion of a nanomechanical resonator may be employed as an absolute thermometer. We experimentally measure radiation pressure shot noise induced quantum correlations to absolutely calibrate the motional signal transduced onto an optical probe.
