Counting Statistics of Many-Particle Quantum Walks
arXiv:1009.5241 · doi:10.1103/PhysRevA.83.062307
Abstract
We study quantum walks of many non-interacting particles on a beam splitter array, as a paradigmatic testing ground for the competition of single- and many-particle interference in a multi-mode system. We derive a general expression for multi-mode particle-number correlation functions, valid for bosons and fermions, and infer pronounced signatures of many-particle interferences in the counting statistics.
