Variational model for the delayed collapse of Bose-Einstein condensates
Variational model for the delayed collapse of Bose-Einstein condensates
We present an action that can be used to study variationally the collapse of Bose-Einstein condensates. This action is real, even though it includes dissipative terms. It adopts long-range interactions between the atoms, so that there is always a stable minimum of the energy, even if the remaining number of …
