  The nonlinear optical dynamics of nano-materials comprised of plasmons
interacting with quantum emitters is investigated by a self-consistent model
based on the coupled Maxwell-Liouville-von Neumann equations. It is shown that
ultra-short resonant laser pulses significantly modify the optical properties
of such hybrid systems. It is further demonstrated that the energy transfer
between interacting molecules and plasmons occurs on a femtosecond time scale
and can be controlled with both material and laser parameters.
