I will discuss some aspects of the physics of fast rotating Boses gases, both from theoretical and experimental perpectives.
From a theoretical point of view, I will address the problem of the vortex pattern expected for these gases at zero temperature in the mean field approximation. I will also describe recent experiments performed in our laboratory [1,2]. In particular I will present our recent study of matter wave interference in an array of (not yet rotating) 2D BEC with uncorrelated phases [2]. This constitutes a promizing system for investigating the properties of layered rotating superfluids. [1] V. Bretin, S. Stock, Y. Seurin, and J. Dalibard, Phys. Rev. Lett. 92, 050403 (2004) [2] Z.
