On point interactions realised as Ter-Martirosyan-Skornyakov Hamiltonians
Alessandro Michelangeli, Andrea Ottolini
For quantum systems of zero-range interaction we discuss the mathematical scheme within which modelling the two-body interaction by means of the physically relevant ultra-violet as…

Mean-field quantum dynamics for a mixture of Bose-Einstein condensates
Alessandro Michelangeli, Alessandro Olgiati
We study the effective time evolution of a large quantum system consisting of a mixture of different species of identical bosons in interaction. If the system is initially prepared…
