摘要

The coherent effects such as forming "dark states," optical pumping, and the stimulated Raman adiabatic passage (STIRAP) are studied in the presence of dielectric and/or metalic nanoparticles. It is shown that the "dark states" are still formed but they have more complicated atomic structure, the optical pumping and the STIRAP cannot be employed in the vicinity of plasmonic nanostructures. Also we show difference of the local atomic polarization and the atomic polarization averaged over ensemble of atoms homogeneously spread near nanoparticles.
