" Theory and experiments with quantum fluids of light:
from superfluid  hydrodynamics to quantum Hall liquids "


Abstract


A few years after the first observation of Bose-Einstein condensation 
in quantum gases of exciton-polaritons in semiconductor microcavities, 
these systems turn out to be very promising candidates for the study of 
  many-body effects in a novel non-equilibrium context.  In this talk, I 
shall first present the recent experiments that have  recently 
demonstrated superfluid hydrodynamics effects in polariton  gases and I 
shall try to address a few conceptual questions on the  meaning of 
superfluidity and Bose-Einstein condensation for non-equilibrium 
systems.  In the second part, I will review a few most significant 
theoretical  advances towards the generation of strongly correlated 
states of photons, from Tonks-Girardeau gases of impenetrable photons in 
1D, to  quantum Hall liquids in the presence of artificial magnetic fields.
