DFG FOR 2414 Annual Workshop 2018
Unit 2414 is a collaboration of experimental groups in
Barcelona, Hamburg and Munich and theoretical groups
Frankfurt am Main, Munich, Göttingen, Hamburg and Paris.
Our goal is to theoretically investigate and experimentally realize novel topological states of
matter induced by synthetic gauge fields in ultracold atoms in optical lattices. In these
setups, atoms are suitably coupled to laser fileds that generate effective gauge potentials.
These systems can mimic the dynamics of electrons moving in a magnetic field, but also the
dynamics of elementary particles in non-Abelian gauge fields. A variety of exotic quantum
phenomena can arise here, where topology plays a fundamental role: from the existence of
topological invariants and topologically protected edge currents to the emergence of quasiparticles with exotic
braiding statistics. These fascinating effects are at the focus of current theoretical and experimental research, as they also
hold the promise to revolutionize quanturm information processing. Thus, the experimental realization of
artificial gauge fields for neutral ultracold atoms has opened a door to the quantum simulation of topological
quantum effects in novel, unprecedentedly well controlled environments. We expect our combined effort to bring both the
theoretical understanding and the experimental realization of topological matter to a new level, paving the way
towards future applications in quantum information processing and spintronics.
