DESCRIPTION:Prof. Jean-Philippe Brantut\, Lab for Quantum Gases\, EPFL\nCa
 vity quantum electrodynamics (QED) is one of the most powerful framework t
 o observe and leverage quantum phenomena. While it has been thoroughly stu
 died for simple quantum systems such as two-level systems or harmonic osci
 llators\, it has only recently become available for complex\, correlated q
 uantum many-body systems. In the last five years\, we have developed syste
 ms combining cavity QED with ultra-cold Fermi gases. In this talk\, I will
  describe these setups\, and some of the intriguing consequences of the in
 terplay of strong atom-atom and strong light-matter coupling. I will then 
 present the use of the cavity to induce long-range interactions between at
 oms\, and show our recent results on density-wave ordering and magnetism i
 nduced by this interaction.  Last I will outline the perspectives open by
  the convergence of cavity QED with complex quantum matter\, in particular
  the possibility of programming cavity-mediated interactions at will and t
 he application of these ideas for condensed matter and high-energy physics
