利用角分辨光谱和时间分辨光谱研究了半导体微腔极化子的动量分布和驰豫动力学。在临界泵浦能级以上，正失谐时极化子的热化时间比它们的寿命短，与晶格处于热平衡状态的极化子形成量子简并的玻色-爱因斯坦分布。
We study the momentum distribution and relaxation dynamics of semiconductor microcavity polaritons by angle-resolved and time-resolved spectroscopy. Above a critical pump level, the thermalization time of polaritons at positive detunings becomes shorter than their lifetime, and the polaritons form a quantum degenerate Bose-Einstein distribution in thermal equilibrium with the lattice.
