On some rigorous aspects of fragmented condensation
Daniele Dimonte, Marco Falconi, Alessandro Olgiati
In this paper we discuss some aspects of fragmented condensation from a mathematical perspective. We first propose a simple way of characterizing finite fragmentation. Then, inspir…
Ground state energy of mixture of Bose gases
Alessandro Michelangeli, Phan Thành Nam, Alessandro Olgiati
We consider the asymptotic behavior of a system of multi-component trapped bosons, when the total particle number becomes large. In the dilute regime, when the interaction pote…
Effective non-linear spinor dynamics in a spin-1 Bose-Einstein condensate
Alessandro Michelangeli, Alessandro Olgiati
We derive from first principles the experimentally observed effective dynamics of a spinor Bose gas initially prepared as a Bose-Einstein condensate and then left free to expand ba…
