Mesoscopic quantum superpositions in bimodal Bose-Einstein condensates: decoherence and strategies to counteract it (1703.07291v2)
Published 21 Mar 2017 in cond-mat.quant-gas and quant-ph
Abstract: We study theoretically the interaction-induced generation of mesoscopic coherent spin state superpositions (small cat states) from an initial coherent spin state in bimodal Bose-Einstein condensates and the subsequent phase revival, including decoherence due to particle losses and fluctuations of the total particle number. In a full multimode description, we propose a preparation procedure of the initial coherent spin state and we study the effect of preexisting thermal fluctuations on the phase revival, and on the spin and orbito-spinorial cat fidelities.
