【 摘 要 】

We study dipole interseries transitions between the yellow and green exciton series in cuprous oxide including the complex valence-band structure. To this end, we extend previous studies of the spectrum of complex green exciton resonances [P. Rommel, P. Zielinski, and J. Main, Phys. Rev. B 101, 075208 (2020)] to optical transitions between different exciton states in addition to transitions from the crystal ground state. This allows us to augment the calculations on interseries transitions using a hydrogenlike model [S. O. Kruger and S. Scheel, Phys. Rev, B 100, 085201 (2019)] by a more comprehensive treatment of the valence-band structure.
