Quantum degeneracy and spin entanglement in ideal quantum gases
Fatma Zouari Ahmed, Mohammed Tayeb Meftah, Tommaso Roscilde
Quantum degeneracy is the central many-body feature of ideal quantum gases stemming from quantum mechanics. In this work we address its relationship to the most fundamental form of…
Compensating the delayed electro-optical deflector response
Marcel Leutenegger, Michael Weber, Henrik von der Emde +1
Due to its immediate response, the electro-optic effect is exploited for high-frequency phase and power modulation and for beam deflection. Besides the immediate response, electro-…
The effect of non-local derivative on Bose-Einstein condensation
F. E. Bouzenna, M. T. Meftah, M. Difallah
In this paper, we study the effect of non-local derivative on Bose-Einstein condensation. Firstly, we consider the Caputo-Fabrizio derivative of fractional order αto derive the eig…
Application of path integral formalism to spectral line broadening: lyman alpha in hydrogenic plasma
M. T. Meftah, Is. Chihi, F. Khelfaoui +2
In this paper the results of Lyman alpha line shapes without the fine structure in the electron impact approximation are rederived using a path integral formalism. The method prese…
