Impurities in degenerate quantum matter

Dr. Meera Parish & Dr. Jesper Levinsen
School of Physics and Astronomy, Monash University, Clayton, Victoria, Australia

The behaviour of a mobile impurity particle interacting with a quantum-mechanical medium is of fundamental importance in physics. Ultracold atomic gases have greatly improved our understanding of the impurity problem owing to the high degree of control over experimental parameters such as interactions and atom population. We will discuss recent theoretical and experimental progress in exploring the properties of impurities interacting with bosonic and fermonic mediums. In particular, we will discuss the effects of finite temperature on the Fermi polaron and the nature of the Bose polaron.
