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

      Knap, Michael; Shashi, Aditya; Nishida, Yusuke; Imambekov, Adilet; Abanin, Dmitry A.; (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 physics can be used to explore new regimes and manifestations of Anderson’s orthogonality catastrophe (OC), which could not be ...
