Bose-Einstein condensates in a double well: mean-field chaos and multi-particle entanglement
Christoph Weiss, Niklas Teichmann
A recent publication [Phys. Rev. Lett. 100, 140408 (2008)] shows that there is a relation between mean-field chaos and multi-particle entanglement for BECs in a periodically shaken…

Creation and detection of a mesoscopic gas in a non-local quantum superposition
Christoph Weiss, Yvan Castin
We investigate the scattering of a quantum matter wave soliton on a barrier in a one dimensional geometry and we show that it can lead to mesoscopic Schrödinger cat states, where t…

Differences between mean-field dynamics and N-particle quantum dynamics as a signature of entanglement
Christoph Weiss, Niklas Teichmann
A Bose-Einstein condensate in a tilted double-well potential under the influence of time-periodic potential differences is investigated in the regime where the mean-field (Gross-Pi…
