From hybrid polariton to dipolariton using non-Hermitian Hamiltonians to handle particle lifetimes

We consider photons strongly coupled to the excitonic excitations of a quantum well, in presence an electric field. show how, under field increase, hybrid polariton made photon carriers lying two wells transforms into dipolariton direct and indirect excitons. also how cavity lifetime coherence time carrier wave vectors that we analytically handle through non-hermitian Hamiltonians affect these polaritonic states. While polaritons display spectral singularity where eigenvalues coalesce, known as exceptional point, depends on detuning lifetimes, find three dipolaritonic states anticrossing without point due interaction between photons, direct,
