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…
Dynamics of Cu2O Rydberg Excitons -- Kerr Effect and Quantum Beats
Gerard Czajkowski
We investigate the nonlinear refraction and the nonlinear Kerr phase shift which are due to Rydberg excitons induced in Cu2O crystal by short-time pulses. We observe the phenomenon…
Dynamics of excitons in CdSe nanoplatelets
Gerard Czajkowski
We show how to calculate the linear and nonlinear optical functions of CdSe nanoplatelets, taking into account the effect of a dielectric confinement on excitonic states. We consid…
Dynamics of CuO Rydberg excitons -- real density matrix approach
Karol Karpinski, Gerard Czajkowski
Basing on recent reliable measurements of the life- and coherence time of CuO Rydberg excitons, we present an analytical method which enables to describe the experimental resul…
Optical properties of excitons in CdSe nanoplatelets and disks: real density matrix approach
David Ziemkiewicz, Gerard Czajkowski, Sylwia Zielińska-Raczyńska
We show how to calculate the optical functions of a nanoplatelet, taking into account the effect of a dielectric confinement on excitonic states. Real density matrix approach is em…
Two-photon absorption in silicon using real density matrix approach
David Ziemkiewicz, David Knez, Evan P. Garcia +7
Two-photon absorption in indirect gap semiconductors is an frequently encountered, but not well-understood phenomenon. To address this, the Real Density Matrix Approach is applied…
