My research is concerned with Bose-Einstein condensates, and in particular with the development of
methods to obtain variationally optimal solutions of the many-body Schrödinger equation.
Thereby, my collaborators and me
could provide the first numerically exact results
on the dynamics of a bosonic Josephson junction.
These results were obtained using the
MCTDHB package
of which I am a developer. If you are interested you can download the
OpenMCTDHB package,
of which I am also a developer.
Very recently, we have invented the concept of 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 Bose-Hubbard
model to the variationally optimal Bose-Hubbard model.
A little while ago, we investigated the ground state of the Lieb-Liniger system as a model for a Bose-Einstein condensates on a ring.
