DESCRIPTION:Speaker: Artem Volosniev\nhosted by Misha Lemeshko\nAbstract: A
 n environment with a mobile impurity particle is the model that is routine
 ly used to understand certain realistic systems\, think of an electron in 
 a crystal or a proton in a neutron star. In spite of the many-body nature 
 of this model\, the low-energy dynamics of the impurity can often be predi
 cted using a single-particle quantum mechanics. This tremendous reduction 
 in complexity can be understood using the polaron quasi-particle -- an imp
 urity 'dressed' by collective excitations (e.g.\, phonons) of the environm
 ent.Motivated by the possibility to create and study polarons in cold-atom
  systems\, I consider a weakly-interacting one-dimensional Bose gas with a
  structureless impurity. My presentation will address the corresponding po
 laron picture\, and the possibility of observing the polaron quasi-particl
 e in current experiments with cold Bose gases. It will also briefly discus
 s induced correlations between two polarons.
