A new SCL's two-year bilateral research project Fast Converging Path Integral Approach to Bose-Einstein Condensation (PI-BEC) has been just approved by the Serbian Ministry of Science and German DAAD agency for the period 2009-2010. This project will provide support to the ongoing collaboration established between SCL's path integral group, led by Dr. Aleksandar Bogojevic, and a research group of Dr. Axel Pelster from the University of Duisburg-Essen, Germany.

The planned research aims to develop a new method for efficiently calculating path integrals by combining previously developed approaches of the two partners: higher order effective actions approach (Serbian group), and recursive diagrammatical approach (German group). The integrated method will be then applied to the study of Bose-Einstein condensation phenomenon. This research will analyze in detail the relation of the new method to other established approaches, such as Variational Perturbation Theory. We also plan to extend our existing Monte Carlo codes so as to implement the above approaches to the study of Bose-Einstein condensation in non-inertial and electromagnetic traps, and in related experimental setups.
