Read e-book online Tunneling Dynamics in Open Ultracold Bosonic Systems: PDF

By Axel U. J. Lode

This thesis addresses the interesting subject of the quantum tunnelling of many-body structures akin to Bose-Einstein condensates. regardless of the big quantity of labor at the tunneling of a unmarried particle via a barrier, we all know little or no about how a approach made up of numerous or of many debris tunnels via a barrier to open space. The present work uses numerically unique recommendations of the time-dependent many-boson Schrödinger equation to discover the wealthy physics of the tunneling to open house procedure in ultracold bosonic debris which are firstly ready as a Bose-Einstein condensate and as a result allowed to tunnel via a barrier to open area. The many-body method is outfitted up from concurrently occurring unmarried particle techniques which are characterised through diversified momenta. those momenta correspond to the chemical potentials of platforms with lowering particle quantity. The many-boson procedure shows interesting collective phenomena: the escaping particles fragment and lose their coherence with the resource and between one another, while correlations build up within the process. The specific realizing of the many-body technique is used to plan and try out a scheme to regulate the ultimate country, momentum distributions or even the correlation dynamics of the tunneling process.
