SUMMARY:Mobile impurities in quantum systems
DESCRIPTION:Featuring Thierry Giamarchi\, University of Geneva\nHosted by: 
	Anatoli Polkovnikov\n\nPart of the Condensed Matter Theory Seminar Series.\
	n\nAbstract:\nThe question of a mobile impurity interacting with a bath\, i
	s a long standing problem of condensed matter physics. The question\, which
	 started with the celebrated Brownian motion\, is now relatively well under
	stood for classical particles. The situation is however much less clear whe
	n the bath and the particle are quantum objects\, a situation relevant for 
	a host of different microscopic realizations ranging from impurities in Hel
	ium to polarons in Fermi liquids. I will discuss here recent results we obt
	ained for the case of one-dimensional quantum bath\, for which novel regime
	s of motion of the impurity appear\, such as sub-diffusive regimes\, and fo
	r which the physics is still largely open. I will also present recent exper
	iments in cold atomic systems probing these phenomena.
