Workshop on Low Dimensional Quantum Gases

Originally, this workshop was led by the late Prof. Mahir Hussein who organized alternating workshops on Nuclear Physics and on Ultracold Atoms and Chaos. Pursuing his ideals, the upcoming São Paulo Workshop deals with Ultracold Atoms. Since the realization of experiments with ultracold atoms in the 90’s, a new field has emerged with themes like atomic Bose-Einstein condensation, BEC-BCS crossover with fermionic atoms, and quantum phase transitions, for instance, with atoms in optical lattices, quantum fluids, nonlinear waves in quantum fluids, etc. In recent years, attention has focused on these systems in constrained geometries, as exemplified most prominently by the recent bubble trap experiments in the Cold Atom Laboratory of the International Space Station. For these reasons, we have decided to focus this workshop on low-dimensional quantum gas physics.

In addition to the invited talks there will be space for contributing posters that will be displayed during the coffee breaks.

This activity will be preceded by the “School on Light and Cold Atoms“. Candidates may apply either for one or both activities.

There is no registration fee.
