In Heidelberg I was working a PhD student and Postdoc on BoseEinstein condensates, in particular on
methods to obtain variationally optimal solutions of the manybody Schrödinger equation.
Thereby, we could provide numerically exact solutions of the timedependent manyboson Schrödinger equation using the
MCTDHB package
of which I am a developer.
We also invented variationally
optimal lattice models, i.e. lattice models that are based
entirely on the principle of least action. These provide a great computational advantage over conventional
lattice models. We showed this by comparing the BoseHubbard
model to the variationally optimal BoseHubbard model.
A while ago, we investigated the ground state of the LiebLiniger system as a model for a BoseEinstein condensates on a ring.
