Abstract

The metal nanoparticle (MNP) can lead to significant reshaping of spectral features in the three level Λ system. For this a master equation is derived with the Born-Markov approximation, but in place of bare states, it’s the dressed states transitions which are coupled to reservoir. This master equation gives many new interesting terms which are not present in traditionally derived master equations. The dressed state-reservoir coupling results in sampling of Local density of states (LDOS) by the dressed state transitions causing asymmetricity in the spectrum.
