Ultracold spinor gases of Rb
Far from equilibrium, comparatively little is known about the possibilities nature reserves for the structure and states of quantum many-body systems. A potential scenario is that these systems can approach a non-thermal fixed point and show …
This thesis examines, along side a series of experiments, the far-from-equilibrium dynamics of isolated quantum many-body systems. As a model example we study the relaxation of a single and two linearly coupled one-dimensional Bose gases, brought …
In this thesis, we study the structure formation following a quench of the detuning of spin exchange. For this, we employ an effective spin-1 87Rb Bose-Einstein condensate in a one-dimensional situation. Bogoliubov theory predicts unstable momentum …
