UConn Physics Colloquium
Cooling of Nanoscale Mirrors
Department of Physics and College of Optical Sciences
University of Arizona
The observation of quantum dynamics in truly macroscopic objects appears increasingly feasible as a result of recent experimental advances that include novel cooling techniques and progress in nanofabrication. This is an exciting prospect, as it would enable us to explore the quantum-classical boundary as well as to test quantum mechanics in an entirely new regime. The implementation of characteristically quantum mechanical phenomena at a macroscopic scale also promises technological benefits for areas from quantum measurement to the interferometric detection of gravitational waves and to atomic force microscopy. A promising route to these objectives is through the use of optomechanical systems, particularly optical cavities where the support of one of the mirrors is a nanoscale cantilever. The talk will review recent developments in the optical cooling of these moving mirrors and discuss the prospects for reaching their quantum mechanical ground state of vibration. Future directions, including the realization of quantum entanglement in these systems, will also be touched upon.
