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…
Superlens with copper and copper oxide
David Ziemkiewicz, Karol Karpiński, Sylwia Zielińska - Raczyńska
We investigate the imaging properties of copper-based superlens surrounded by copper oxide (CuO). A subwavelength image resolution of the order is demonstrated theoretica…
Copper plasmonics with excitons
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
We investigate the propagation of surface plasmons (SPPs) in a thin layer of copper surrounded by copper oxide CuO. It is shown that particularly strong excitons in CuO can…
Nonlinear optical properties and Kerr nonlinearity of Rydberg excitons in CuO quantum wells
David Ziemkiewicz, Gerard Czajkowski, Karol Karpiński +1
The quantum confiment of Rydberg excitons (REs) in quantum structures opens the way towards considering nonlinear interactions in such systems. We present a theoretical calculation…
