  We study arrays of plasmonic nanoparticles combined with quantum emitters,
quantum plasmonic lattices, as a platform for room temperature studies of
quantum many-body physics. We outline a theory to describe surface plasmon
polariton distributions when they are coupled to externally pumped molecules.
The possibility of tailoring the dispersion in plasmonic lattices allows
realization of a variety of distributions, including the Bose-Einstein
distribution as in photon condensation. We show that the presence of losses can
relax some of the standard dimensionality restrictions for condensation.
