Description de la mission

The quantum Hall effect is one of the most remarkable phenomena in condensed-matter physics [1] and in important effort is currently devoted in reproducing it in a controllable cold-atom setup [2].
In this internship we will take advantage of one of the intrinsic properties of ultra-cold atoms, namely the fact that they are lossy. This feature, often regarded as an important disadvantage, has recently attracted a significant amount of interest, because it can be used to drive the gas into regimes that do not have a counterpart in equilibrium situations [3].
In particular, we will start from the observation that several notable states of the bosonic quantum Hall effect, such as the Laughlin wavefunction at filling ½, are immune to losses and are a stationary state of the lossy dynamics.
The goal of this internship is to characterize the dynamics of a rotating bosonic gas and to study the stationary states where the gas is driven by the lossy dynamics.
