Coherence and superfluidity are hallmark properties of cold quantum matter. With the achievement of Bose-Einstein condensation and fermionic superfluidity in atomic gases, it is now possible to study these phenomena in a clean and well controlled environment. The possibility to engineer the trapping geometry and the strength of interactions provides a way to simulate the rich dynamics of condensed-matter systems.

The investigation of low dimension gases is of particular interest in this context, since the phase transitions that a system can undergo depends crucially on its dimensionality. The talk will review recent progresses in this direction, and address in particular the specific properties of 2D atomic gases. The key role played by quantized vortices will be emphasised and connections with other domains of macroscopic quantum physics, such as Quantum Hall phenomena, will be discussed.
