Quantum Breathing of an Impurity in a One-Dimensional Bath of Interacting Bosons:
Author(s): Sebastiano Peotta, Davide Rossini, Marco Polini, Francesco Minardi, and Rosario Fazio
By means of the time-dependent density-matrix renormalization-group (TDMRG) method we are able to follow the real-time dynamics of a single impurity embedded in a one-dimensional bath of interacting bosons. We focus on the impurity breathing mode, which is found to be well described by a single osci...
