Plasmon-enhanced quadrupole transitions of Rydberg excitons in Cu2O
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
A mechanism for amplification of weak quadrupole transitions of Rydberg excitons in CuO by a plasmonic nanostructure is investigated. The theoretical description of exciton-pla…

Quantum interference of Rydberg excitons in Cu0: quantum beats
Sylwia Zielińska-Raczyńska, David Ziemkiewicz
A density matrix formalism is employed to calculate the emission of multi-level excitonic system, highlighting picosecond-scale dynamics and coherent effects such as quantum beats.…
