Phys. Rev. Lett. 100, 110404 (2008) [4 pages]Andreev-Like Reflections with Cold AtomsReceived 14 October 2007; published 20 March 2008 We propose a setup in which Andreev-like reflections predicted for 1D transport systems could be observed time dependently using cold atoms in a 1D optical lattice. Using time-dependent density matrix renormalization group methods we analyze the wave packet dynamics as a density excitation propagates across a boundary in the interaction strength. These phenomena exhibit good correspondence with predictions from Luttinger liquid models and could be observed in current experiments in the context of the Bose-Hubbard model. © 2008 The American Physical Society URL:
