Emergence of mesoscopic entanglement for a Bose-Einstein condensate in a double well with time-dependent potential differences — •Bettina Gertjerenken, Stephan Arlinghaus, Niklas Teichmann, and Christoph Weiss — Institut für Physik, Carl von Ossietzky Universität, D-26111 Oldenburg, Germany

We explore the relation between mean-field chaos and multi-particle entanglement for a Bose-Einstein condensate in a periodically shaken double well [1]. The entanglement-flag used to identify mesoscopic entenglement is the quantum Fisher information.
