Obtaining equations of motion for a three-level atom and plasmon system

$\textbf{Question:}$ I intend to find the equations of motion for the expectation values of the plasmon and atomic annihilation operators ($\langle \hat{a} \rangle$, $\langle \hat{\sigma}_{12} \rangle$ … With the atom being a three level system and the plasmon operators being two level, is it possible to use the trace as follows for this purpose? …

Deriving coupled equations of motion using optical master equation for atom-plasmon system

I came across the following scenario describing the interaction between a two level atom and a single surface plasmon mode in a metal nano-particle under the classical driving field $ E_i = E_0e^{-i\omega … ^\dagger$ be the lowering and raising operators of the atom and $\omega_{sp}$ and $\omega_x$ be the plasmon and atomic resonance frequencies respectively. …

How do I derive and use the effective hamiltonian for plasmon-exciton coupled system to obta...

Consider the interaction of a single surface plasmon mode in a metal nanoparticle with a dipole emitter(atom) under the classical driving field $ E_i = E_0e^{-i\omega t} + c.c $ , with the following Hamiltonian … of the atom and $\omega_{sp}$ and $\omega_x$ be the plasmon and atomic resonance frequencies respectively. …
