Thermodynamics of Charged AdS Black Holes in Extended Phases Space via M2-branes Background
M. Chabab, H. EL Moumni, K. Masmar
Motivated by a recent work on asymptotically Ad black holes in M-theory, we investigate both thermodynamics and thermodynamical geometry of Raissner-Nordstrom-AdS black holes…
Quantum discord in photon added Glauber coherent states of -type
M. Daoud, W. Kaydi, H. El Hadfi
We investigate the influence of photon excitations on quantum correlations in tripartite Glauber coherent states of Greenberger-Horne-Zeilinger type. The pairwise correlations are…
A Contribution in the Rotor-router model
Hassan Douzi
In this paper I propose to approach the Rotor-router problem by considering it as one example of a big family of many other similar models. The study of some specific samples of th…
Quantum correlations beyond entanglement in a double-cavity opto-mechanical system
J. El Qars, M. Daoud, Ahl Laamara
In this paper we investigate the robustness of the quantum correlations against the environment effects in various opto-mechanical bipartite systems. For two spatially separated op…
A polynomial class of algebras
M. Daoud, W. S. Chung
A -parameter algebra is introduced. Finite unitary representations are investigated. This polynomial algebra reduces via a contraction proce…
Hilbert-Schmidt measure of pairwise quantum discord for three-qubit states
M. Daoud, R. Ahl Laamara, S. Seddik
The Hilbert-Schmidt distance between a mixed three-qubit state and its closest state is used to quantify the amount of pairwise quantum correlations in a tripartite system. Analyti…
