SUMMARY:Quantum Measurement Backaction : From single atoms to mesoscopic op
	tomechanical systems
DESCRIPTION:Featuring Mukund Vengalattore\, Cornell\nHosted by: Anatoli Pol
	kovnikov\n\nPart of the Biophysics/Condensed Matter Seminar Series.\n\nThe 
	act of measurement has profound consequences on a quantum system. As such\,
	 the evolution of a quantum system can be influenced and even controlled th
	rough the continuous measurement of its properties. I will describe our stu
	dies on such measurement-induced dynamics in systems ranging from nanoKelvi
	n atomic gases to millimeter-scale mechanical systems. In the former case\,
	 we demonstrate that the act of imaging ultracold atoms can influence their
	 quantum motion - a manifestation of the Quantum Zeno effect. We show that 
	such continuous measurement schemes can be employed to induce new forms of 
	collective quantum behavior and as such\, are a promising avenue to the stu
	dy of open quantum systems and the interplay between coherent quantum dynam
	ics and dissipation. I will also discuss our ongoing efforts to extend such
	 measurement-backaction schemes to control mesoscopic optomechanical system
	s for applications including quantum metrology and the study of non-equilib
	rium dynamics of isolated quantum systems.
