SUMMARY:From classical to quantum chaos:Where are we now?
DESCRIPTION:Featuring F. M. Izrailev\, Instituto de Fisica\, BUAP\, Mexico\
	, and Michigan State University\nHosted by: Anatoli Polkovnikov\n\nPart of 
	the Condensed Matter Theory Seminar Series.\n\nAbstract:\nIn this lecture w
	e discuss the evolution of our understanding of dynamical chaos emerging in
	 physical systems. We start with mentioning first studies of classical chao
	s\, motivated in early 1957-1967 by practical problems of stability of moti
	on of charged particles in accelerators. With the use of a simple model we 
	show the meaning of Chirikov criterion of overlapping resonances that allow
	s one to find the conditions under which dynamical systems begin to behave 
	in a very irregular way. We demonstrate the effectiveness of this criterion
	 in resolving famous Fermi-Pasta-Ulam problem\, originated by the first "co
	mputer experiment". Then we pass to quantum systems paying main attention t
	o the meaning of quantum chaos. We conclude our lecture with a brief discus
	sion of open problems of many-body chaos in systems of interacting Fermi an
	d Bose particles.
