Emission Dynamics of Rydberg Excitons in : Distinguishing Second Harmonic Generation from Secondary Emission
Kerwan Morin, Poulab Chakrabarti, Delphine Lagarde +5
Rydberg excitons in simultaneously give rise to two very different optical responses under resonant two-photon excitation: a coherent second-harmonic signal mediat…
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…
Tunable Rydberg excitons maser
D. Ziemkiewicz, S. Zielińska - Raczyńska
We propose a solid state maser based on Cu2O, where ensemble of highly excited Rydberg exciton states serves as a gain medium. We show that the system is highly tunable with extern…
Tunable narrow-band plasmonic resonances in electromagnetically-induced-transparency media
David Ziemkiewicz, Karolina Słowik, Sylwia Zielińska - Raczyńska
The spectral response of a plasmonic nanostructure may heavily depend on the refractive index of its surroundings. The key idea of this paper is to control this response by coheren…
