Zusammenfassung

The project involves various aspects of the theoretical and numerical investigations of the Bose-Einstein condensation (BEC) in the framework of the quantum field theoretical and Quantum Monte Carlo (numerical) methods. The phase transitions into the BEC of both homogeneous and magnetically trapped atomic gases, as well as the superfluidity of 4He in porous media will be considered. The critical temperatures, critical exponents, structure factors and other properties of the transitions will be investigated. The results and theoretical predictions of the project will give a new and sign...
