Electro-optical properties of excitons in CuO quantum wells: II continuum states
David Ziemkiewicz, Gerard Czajkowski, Karol Karpiński +1
We present theoretically calculated optical functions for CuO quantum well (QW) with Rydberg excitons in an external, homogeneous electric field parallel to the QW planes for t…
Electro-optical properties of excitons in CuO quantum wells: I discrete states
David Ziemkiewicz, Gerard Czajkowski, Karol Karpiński +1
We present theoretical results of the calculations of optical functions for CuO quantum well (QW) with Rydberg excitons in an external homogeneous electric field of an arbitrar…
Fractional Derivative Modification of a Drude Model
Karol Karpiński, Sylwia Zielińska - Raczyńska, David Ziemkiewicz
A modification of the Drude dispersive model based on fractional time derivative is presented. The dielectric susceptibility is calculated analytically and simulated numerically, s…
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…
