泵浦极化激元系统的稳态密度矩阵

Stationary density matrix of a pumped polariton system

Carlos Andres Vera, Alejandro Cabo, Augusto Gonzalez

摘要:

从考虑泵浦和损耗的主方程出发,数值计算了模型极化激元系统的密度矩阵ρ。在定态极限下,哈密顿量的本征态之间的相干性比占位小三个数量级,这意味着定态密度矩阵在能量表示中近似为对角。弱扭曲巨正则吉布斯分布很好地拟合了职业。

英文摘要:

The density matrix, ρ, of a model polariton system is obtained numerically from a master equation which takes account of pumping and losses. In the stationary limit, the coherences between eigenstates of the Hamiltonian are three orders of magnitude smaller than the occupations, meaning that the stationary density matrix is approximately diagonal in the energy representation. A weakly distorted grand canonical Gibbs distribution fits well the occupations.
