Quantum defects of Rydberg excitons in cuprous oxide: A semiclassical spherical model
Jan Ertl, Patric Rommel, Jörg Main
Excitons, i.e. the bound states of an electron and a positively charged hole are the solid state analogue of the hydrogen atom. As such they exhibit a Rydberg series, which in cupr…

Rydberg excitons in cuprous oxide: A two-particle system with classical chaos
Jan Ertl, Sebastian Rentschler, Jörg Main
When an electron in a semiconductor gets excited to the conduction band the missing electron can be viewed as a positively charged particle, the hole. Due to the Coulomb interactio…

Classical dynamics and semiclassical analysis of excitons in cuprous oxide
Jan Ertl, Michael Marquardt, Moritz Schumacher +3
Excitons, as bound states of electrons and holes, embody the solid state analogue of the hydrogen atom, whose quantum spectrum is explained within a classical framework by the Bohr…
