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…
Numerical analysis of grasshopper escapement
David Ziemkiewicz
The dynamics of driven, damped pendulum as used in mechanical clocks is numerically investigated. In addition to the analysis of a well-known mechanisms such as chronometer escapem…
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…
