A European network activity is proposed on the novel states of matter in dilute quantum systems, that is ultracold atomic and molecular gases in magnetic and other traps. The programme builds on the synergy which was achieved in the ESF PEN (formerly PESC) Programme “BEC2000+ -- Bose-Einstein Condensation and beyond”. The new programme adopts the current trends and developments of the field, which comprises degenerate Fermi gases, mixtures of Bose- and Fermi systems, homo- and heteronuclear molecular systems and even quantum phase transitions in the strongly interacting regime. Operational activities of the programme consist in the organization and support of conferences and workshops, a variety of visiting programmes, and a long-term fellowship programme for young researchers.
