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…
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…
