论文摘要
我们在一个广义的哈伯族哈密顿量的框架中实施了外部激发的ZnO MIE共振器，以从热力学平衡中调查激子和激子 - 果棒的生命。我们的结果是通过动力学均值理论（DMFT）和二阶迭代扰动理论求解器（IPT）的Floquet-keldysh-Green形式主义得出的。我们发现，FANO共振源自状态的电子密度与半导体MIE谐振器的耦合产生寿命为0.6 PS和1.45 PS的极性。将这些结果与ZnO Polariton激光器和ZnO随机激光器进行了比较。我们将结果寿命的峰值解释为增益变窄的迹象，这可能会导致单个激发ZnO MIE谐振器中稳定的Polariton激光模式。这种形式的增益可能会导致在非平衡元素中ZnO MIE共振器合奏中的偏振子随机激光。
We implement externally excited ZnO Mie resonators in a framework of a generalized Hubbard Hamiltonian to investigate the lifetimes of excitons and exciton-polaritons out of thermodynamical equilibrium. Our results are derived by a Floquet-Keldysh-Green's formalism with Dynamical Mean Field Theory (DMFT) and a second order iterative perturbation theory solver (IPT). We find that the Fano resonance which originates from coupling of the continuum of electronic density of states to the semiconductor Mie resonator yields polaritons with lifetimes between 0.6 ps and 1.45 ps. These results are compared to ZnO polariton lasers and to ZnO random lasers. We interpret the peaks of the exciton-polariton lifetimes in our results as a sign of gain narrowing which may lead to stable polariton lasing modes in the single excited ZnO Mie resonator. This form of gain may lead to polariton random lasing in an ensemble of ZnO Mie resonators in the non-equilibrium.
