Abstract: The main objective of the project is to put the new experimental laboratory at the BEC Center in Trento in a position to quickly reach the highest operational level, extending the group with graduate students and postdoctoral fellows, completing the purchase of equipment and supporting the expenses for the first measurement campaigns on condensates of sodium and, subsequently, on mixtures of potassium and sodium. Another important goal of the project is to direct part of the theoretical activities of the Center to create synergies with the experiments, creating a solid relationship between the two cores of the Center, theoretical one and experimental one, as well as between them and their network international collaborations.
