Group seminar LMU: From Superfluidity to Entanglement with Bose-Einstein Condensates

Two central features of dilute Bose-Einstein condensate (BEC) gases are the tunable nonlinearity with respect to the bosonic field operator and the small depletion. These allow for the investigation of different classes of phenomena, ranging from the existence of persistent currents in toroidal traps to the creation of particle entanglement. In particular, we’ll show that entanglement can be physically related to the distinguishability of quantum states. This has different implications, from ultra-precise interferometric phase estimations to the creation of quantum Zeno dynamics.
