Dissipative Rabi model in the dispersive regime

open access: yesPhysical Review Research, 2020
The dispersive regime of circuit QED is the main workhorse for today's quantum computing prototypes based on superconducting qubits. Analytic descriptions of this model typically rely on the rotating-wave approximation of the interaction between the ...

A simplified mathematical theory of MHD power generators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
We present a simplified version of the Faraday magnetohydrodynamics (MHD) generators theory. The effect of the Loretz force against the fluid ow is neglected, whence it follows the uniform ow of the plasma. We use Lazăr Dragoș’s analytic solution for the

Analytical solutions using special trans functions theory for current–voltage expressions of perovskite solar cells and their approximate equivalent circuits

open access: yesAin Shams Engineering Journal, 2023
Perovskite solar cells (PSC) have been recognized as devices with a constant increase in power conversion efficiency, confirming this promising technology’s upward trend. This paper deals with the mathematical modeling of current voltage and inverse voltage-current relationships of PSCs, in which standard equivalent circuits, as well as approximate ...
