摘要: Abstract We study the dynamics of polaritons in Keldysh functional formalism. Dissipation is considered through coupling exciton and photon fields to two independent photonic excitonic baths. As such, this theory allows describe more intricate decay mechanisms that depend dynamically on state system, such as a direct upper-polariton lifetime, motivated from experiments. show resulting dynamical equations based formalism otherwise follow same Josephson–like motions than standard master equation approach, however limited simple channels. also discuss stability reconsider criterion strong presence upper polariton decay.
