Entanglement Dynamics of Ultra-Cold Atoms in Optical Superlattices — •Andreas Wagner, Thomas L. Schmidt, and Christoph Bruder — Universität Basel

We study the dynamics of ultra-cold atoms in optical superlattices and entanglement in such multipartite systems. We investigate and compare different ways to quantify and manipulate entanglement of three to four atoms, which are trapped in such a lattice and form a subsystem of a larger amount of trapped atoms. By manipulating the lattice we get information about the dynamics of entanglement distribution.
