Many-body interference is a purely quantum mechanical interference effect that arises in transitions of many identical particles if the particles are at least to some degree indistinguishable. It non-trivially affects the particles’ collective dynamics and features diverse promising quantum information schemes such as optical quantum computation or simulations of quantum many-body problems with ultracold atoms in optical lattices.
In this talk I give an introduction to some of our research activities related to many-body interference. First I concentrate on finite-dimensional quantum systems, discuss the role of the particle’s indistinguishability for many-body interference, and show how many-body indistinguishability can be quantified and experimentally characterized. Thereafter I turn to infinite-dimensional systems of many interacting particles. I show how we can numerically study the exact many-body dynamics using finite element methods and show some preliminary results for paradigmatic examples.
