The aim of this proposal is the systematic theoretical investigation ofexcitons in external electric and magnetic fields in a solid state likecuprous oxide. The important point is to learn about the combinedinteraction of excitons with the complete structure of the valenceband, the external fields, and the phonon states. Detailedcomparisons of computed and experimental spectra of excitons inexternal fields allow for the calibration of the field strengths and thedetermination of accurate material constants of cuprous oxide. Higherelectric field strengths as well as the exciton-phonon interaction leadto broadened line shapes in the photoabsorption spectra and give riseto fundamental quantum signatures of open many degrees systemssuch as Ericson fluctuations and exceptional points.

这一计划的目的是系统的理论研究激子在外部电场和磁场中的固态氧化亚铜。重要的一点是了解激子与价带、外场和声子态的完整结构的组合相互作用。详细比较了外场中激子的计算谱和实验谱，从而可以对外场强度进行校准，并精确确定氧化亚铜的材料常数。较高的电场强度以及激子-声子相互作用导致光吸收谱中的线宽变宽，并产生了许多开放度系统的基本量子特征，如Ericson涨落和例外点。
