论文摘要
我们在数值上研究了氧化热的绿色激子系列的奇数奇偶校验状态。考虑到与黄色系列的耦合，尤其是在黄色连续体中，绿色激子是准结合的共鸣，具有有限的寿命，无法与Hermitian操作员一起描述。为了计算它们的位置和线宽，我们使用复杂坐标旋转的方法，导致非热综合特征值问题。我们发现，使用负量子缺陷的修改后的Rydberg公式非常近似主要的P状态的行为。与主量子数的第三强度，与黄色连续体相连引起的相应线宽降低。
We numerically investigate the odd parity states of the green exciton series in cuprous oxide. Taking into account the coupling to the yellow series and especially to the yellow continuum, the green excitons are quasi-bound resonances with a finite lifetime which cannot be described with Hermitian operators. To calculate their positions and linewidths, we use the method of complex-coordinate rotation, leading to a non-Hermitian complex eigenvalue problem. We find that the behavior of the dominant P states is very well approximated by a modified Rydberg formula using a negative quantum defect. The corresponding linewidths induced by the coupling to the yellow continuum decrease with the third power of the principal quantum number.
