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…

Reconstruction of quasi-local numerical effective models from low-resolution measurements
Alfonso Caiazzo, Roland Maier, Daniel Peterseim
We consider the inverse problem of reconstructing an effective model for a prototypical diffusion process in strongly heterogeneous media based on coarse measurements. The approach…
