Riemannian optimisation methods for ground states of multicomponent Bose-Einstein condensates
R. Altmann, M. Hermann, D. Peterseim +1
This paper addresses the computation of ground states of multicomponent Bose-Einstein condensates, defined as the global minimiser of an energy functional on an infinite-dimensiona…

A novel energy-based modeling framework
R. Altmann, P. Schulze
We introduce an energy-based model, which seems especially suited for constrained systems. The proposed model provides an alternative to the popular port-Hamiltonian framework and…
