Physics - Colloquium

In cavity optomechanical systems, the motion of a mechanical element is sensed by its influence on the field within an electromagnetic resonator.  While their experimental realizations are diverse, with mechanical elements ranging from picogram-scale nanofabricated filaments to the kilogram-scale mirrors of the LIGO detector and optical systems ranging from stripline resonators to kilometers-long optical cavities, such systems are converging on the common goal of quantum limited operation.  I will discuss the use of ensembles of ultracold trapped atoms as mechanical elements within a high-finesse optical cavity.  With this system, we realize cavity optomechanics in a regime where both the "opto" and the "mechanics" portions of the hybrid system show distinct quantum mechanical features.
