Here we demonstrate high-precision multi-band spectroscopy in a...1 January 2018|ILP SengstockSymmetry-broken momentum distributions induced by matter-wave diffraction during time-of-flight expansion of ultracold atomsPhoto: AG SengstockWe study several effects which lead to symmetry-broken momentum distributions of quantum gases released from optical lattices. In particular, we...Previous articles
