Eyal Buks: Back-reaction Effects in Optomechanical Cavities

Monday, October 27, 2014 2:30 pm - 3:30 pm EDT (GMT -04:00)

Eyal Buks, Technion – Israel Institute of Technology

The field of cavity optomechanics deals with a family of systems, each is composed of two coupled elements. The first one is a mechanical resonator, commonly having low damping rate, and the second one is an ancilla system, which is typically externally driven. The talk will be devoted to three configurations: a mechanical opto-microwave cavity [1] , an on-fiber optomechanical cavity [2] , and a vibrating superconducting quantum interference device (SQUID) [3]. A variety of phenomena will be discussed including linear and nonlinear spring effect, mode cooling, super-critical and sub-critical Hopf bifurcation and self-excited oscillation. The feasibility of experimental exploration of non-classicality at a macroscopic scale in the systems under study will be briefly discussed.
