Cel This project brings together Russian theoreticians and experimental research groups in western Europe in the field of quantum collective phenomena at low temperature. The project is directed towards the investigation of strongly correlated electron systems, amorphous materials and dilute Bose systems at low and ultra-low temperatures. The common denominator arises from important recent theoretical contributions to these topics by the Russian participants and the desire of the west European participants to organise a proper scientific interaction where the interrelation between spin and charge degrees of freedom in heavy fermion (HF) compounds and the influence of high magnetic field on the ground state and collective excitations will be studied. To reveal the origin of spectral properties of strongly correlated electron systems special attention will be paid to the theory of the De Haas-van Alphen effect in HF compounds and type-II superconductors.Low-energy collective excitations in amorphous materials and polycrystalline disordered materials, originating from dynamical interaction between two-level systems, will be investigated. The existence of collective excitations should allow the change of relaxational mechanisms at ultra-low temperatures to be explained and set up the basic representation for the formation of universal properties of glasses, in particular the interaction between tunnelling states and phonons. The investigation of dilute Bose systems will be focused on the formation kinetics of a Bose-Einstein condensate (BEC) and its optical signature in one- and two-photon spectroscopy. The theory, including the formation of quantum correlations, will be developed for metastable inhomogeneous systems such as excitonic gas in semiconductors and trappable atomic gases (atomic hydrogen, alkaline atoms, triplet helium).
