# Exciton mass and exciton spectrum in the cuprous oxide

@article{Alvermann2017ExcitonMA, title={Exciton mass and exciton spectrum in the cuprous oxide}, author={A. Alvermann and Holger Fehske}, journal={Journal of Physics B: Atomic, Molecular and Optical Physics}, year={2017}, volume={51} }

Excitons with a radius of a few lattice constants can be affected by strong central-cell corrections, leading to significant deviations of the optical spectrum from the hydrogen-like Rydberg series, and also to an enhancement of the exciton mass. We present an approach to this situation based on a lattice model that incorporates the effects of a non-parabolic band structure, short distance corrections to the Coulomb interaction between electrons and holes, spin–orbit and exchange coupling. The…
