Quantum confined Rydberg excitons in CuO nanoparticles
Konstantinos Orfanakis, Sai Kiran Rajendran, Hamid Ohadi +4
The quantum confinement of Rydberg excitons is an important step towards exploiting their large nonlinearities for quantum applications. We observe Rydberg excitons in natural nano…
Rydberg Magnetoexcitons in CuO Quantum Wells
David Ziemkiewicz, Gerard Czajkowski, Karol Karpiński +1
We present theoretical approach that allows for calculation of optical functions for CuO Quantum Well (QW) with Rydberg excitons in an external magnetic field of an arbitrary f…
Excitons in Cu2O -- from Quantum Wells to Bulk Crystals and Additional Boundary Conditions for Rydberg Exciton-Polaritons
David Ziemkiewicz, Karol Karpiński, Sylwia Zielińska-Raczyńska +1
We propose a scheme for calculation of optical functions of a semiconductor with Rydberg excitons, for a wide interval of dimensions. We start with 2-dimensional structure, then go…
Nonlinear Optical Properties and Self-Kerr Effect of Rydberg Excitons in CuO
Sylwia Zielińska-Raczyńska, Gerard Czajkowski, Karol Karpiński +1
We show how to compute the nonlinear optical functions (absorption, reflection, and transmission) for a medium with Rydberg excitons, including the effect of the coherence between…
Electro-optical properties of CuO in the regime of Franz-Keldysh oscillations
Sylwia Zielińska-Raczyńska, David Ziemkiewicz, Gerard Czajkowski
We present the analytical method enables one to compute the optical functions i.e., reflectivity, transmission and absorption including the excitonic effects for a semiconductor cr…
Electromagnetically Induced Transparency and slow light in media with Rydberg Excitons
Sylwia Zielińska-Raczyńska, David Ziemkiewicz, Gerard Czajkowski
We show that the Electromagnetically Induced Transparency (EIT) is possible in a medium exhibiting Rydberg excitons and indicate the realistic parameters to perform the experiment.…

We show how to compute the optical functions when Rydberg Excitons appear, including the effect of the coherence between the electron-hole pair and the electromagnetic field. We us…
Frequency shifts of radiating particle moving in EIT metamaterial
S. Zielińska-Raczyńska, D. Ziemkiewicz
Nowadays, there is considerable interest in metamaterials which realize the electromagnetically induced transparency in a classical system. We consider the frequency shifts of part…

Sylwia Zielińska-Raczyńska, Gerard Czajkowski, David Ziemkiewicz
We show how to compute the optical functions of Wide Parabolic Quantum Wells (WPQWs) exposed to uniform electric F applied in the growth direction, in the excitonic energy region.…
Combined complex Doppler and Cherenkov effect in left-handed metamaterials
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
We derive the formula of the complex Doppler shift in a two-dimensional, dispersive metamaterial and we show that a moving, monochromatic radiation source generates multiple freque…
Complex Doppler effect in left-handed metamaterials
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
The Doppler shift is investigated in one-dimensional system with moving source. Theoretical findings are confirmed in numerical simulations of optical and acoustical waves propagat…
