Rydberg excitons in core-shell nanostructures II. Plasmon-exciton interaction and enhancement
David Ziemkiewicz, Gerard Czajkowski, Sylwia Zielińska-Raczyńska
Interaction between Rydberg excitons in core-shell CuO nanostructures and surface plasmons is investigated. An enhancement of a quadrupole transitions to the Rydberg exciton st…
Rydberg excitons in core-shell nanostructures I. Optical properties
Sylwia Zielińska-Raczyńska, Gerard Czajkowski, David Ziemkiewicz
Optical properties of CuO-metal core-shell nanostructures containing Rydberg excitons are examined. Calculations of electron and hole eigenfunctions and eigenenergies are used…
Propagation processing of short pulses in Rydberg exciton medium under blockade conditions
Sylwia Zielińska-Raczyńska, David Ziemkiewicz
Propagation of short pulses through CuO crystal containing Rydberg excitons is studied with the use of density matrix formalism and FDTD method. Saturation effects related to t…
Emission Dynamics of Rydberg Excitons in : Distinguishing Second Harmonic Generation from Secondary Emission
Kerwan Morin, Poulab Chakrabarti, Delphine Lagarde +5
Rydberg excitons in simultaneously give rise to two very different optical responses under resonant two-photon excitation: a coherent second-harmonic signal mediat…
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.…
