  • Olgiati, Alessandro (SISSA, 2017-02)
    We report on a recent result concerning the effective dynamics for a mixture of Bose-Einstein condensates, a class of systems much studied in physics and receiving a large amount of attention in the recent literature in ...
  • Michelangeli, Alessandro; Olgiati, Alessandro (2018-03)
    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 ballistically. In spinor condensates, which ...
  • Michelangeli, Alessandro; Olgiati, Alessandro (2017-04-03)
    We derive the equations for the non-linear effective dynamics of a so called pseudo-spinor Bose-Einstein condensate, which emerges from the linear many-body Schrödinger equation at the leading order in the number of ...
  • Michelangeli, Alessandro; Thanh Nam, Phan; Olgiati, Alessandro (2018-03)
    We consider the asymptotic behavior of a system of multi-component trapped bosons, when the total particle number N becomes large. In the dilute regime, when the interaction potentials have the length scale of order ...
  • Michelangeli, Alessandro; Olgiati, Alessandro (2016-02-02)
    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 so as to exhibit condensation in each ...
  • Olgiati, Alessandro (2017-03-30)
    The effective dynamics for a Bose-Einstein condensate in the regime of high dilution and subject to an external magnetic field is governed by a magnetic Gross-Pitaevskii equation. We elucidate the steps needed to adapt ...
  • Michelangeli, Alessandro; Olgiati, Alessandro; Scandone, Raffaele (2017)
    We establish the local and global theory for the Cauchy problem of the singular Hartree equation in three dimensions, that is, the modification of the non-linear Schrödinger equation with Hartree non-linearity, where ...
