If the system is initially prepared so as to exhibit condensation in each component, we prove that condensation persists at later times and we show quantitatively that the many-body SchrÃ¶dinger dynamics is effectively described by a system of coupled cubic non-linear SchrÃ¶dinger equations, one for each component.1 aMichelangeli, Alessandro1 aOlgiati, Alessandro uhttp://urania.sissa.it/xmlui/handle/1963/35172
