State transition control of emitter chain coupled to surface plasmon polariton

In this paper, the behavior of the coupled emitters inside a monochromatic laser field is investigated. The Hamiltonian of the system is obtained using the tensor product of the single emitter Hamiltonian and adding the interaction terms. The population of the states for each emitter is calculated by numerical solving of the time dependent Schrodinger equation. The results show that the transition occurs at a resonance frequency for any values of laser intensity. Also, the resonance frequency depends on the coupling strength of the system. Furthermore, the transition probability increases with increasing the laser intensity at each laser frequency and coupling strength.
