SUMMARY:Nonlinear Optomechanics: quadratic coupling and the single-photon r
	egime
DESCRIPTION:Featuring Andreas Nunnenkamp\, Yale University\n\nPart of the C
	ondensed Matter Theory Seminar Series.\n\nAbstract:\n In optomechanical sys
	tems optical and mechanical degrees of freedom are coupled via radiation pr
	essure\, optical gradient and photothermal forces. Optomechanical devices m
	ay find applications in precision measurement\, quantum information setups 
	and studies of the quantum-to-classical transition.\n \n To date\, the lite
	rature has focused on the linear regime of systems where the position of th
	e mechanical oscillator is coupled parametrically to the cavity. For exampl
	e\, the recently demonstrated red-sideband cooling and normal-mode splittin
	g can be explained in the framework.\n \n To prepare non-Gaussian states\, 
	however\, one has to go beyond this linear setting. In particular\, I will 
	discuss the regime where a single photon displaces the oscillator by more t
	han its zero-point uncertainty [arXiv:1103.2788] and systems where the posi
	tion of the mechanical oscillator squared is coupled parametrically to the 
	cavity [PRA 82\, 021806(R) (2010)].
