    • Time-Dependent Impurity in Ultracold Fermions: Orthogonality Catastrophe and Beyond 

      Knap, Michael; Shashi, Aditya; Nishida, Yusuke; Imambekov, Adilet; Abanin, Dmitry A.; Demler, Eugene (2012)
      The recent experimental realization of strongly imbalanced mixtures of ultracold atoms opens new possibilities for studying impurity dynamics in a controlled setting. In this paper, we discuss how the techniques of atomic ...
