Query: Strong photon blockade with intracavity electromagnetically induced
  transparency in blockaded Rydberg ensemble   We consider the dynamics of intracavity electromagnetically induced
transparency (EIT) in an ensemble of strongly interacting Rydberg atoms. By
combining the advantage of variable cavity lifetimes with intracavity EIT and
strongly interacting Rydberg dark-state polaritons, we show that such
intracavity EIT system could exhibit very strong photon blockade effect.
