Gap-tunable of Tunneling Time in Graphene Magnetic Barrier
Youssef Fattasse, Miloud Mekkaoui, Ahmed Jellal +1
We study the tunneling time of Dirac fermions in graphene magnetic barrier through an electrostatic potential and a mass term. This latter generates an energy gap in the spectrum a…
Effect of Strain on Band Engineering in Gapped Graphene
Hasna Chnafa, Miloud Mekkaoui, Ahmed Jellal +1
We study the effect of strain on the band engineering in gapped graphene subject to external sources. By applying the Floquet theory, we determine the effective Hamiltonian of elec…
Purity Temperature Dependent for Coupled Harmonic Oscillators
Abdeldjalil Merdaci, Ahmed Jellal, Ayman Al Sawalha +1
We consider the thermal aspect of a system composed of two coupled harmonic oscillators and study the corresponding purity. We initially consider a situation where the system is br…
Energy Levels of Quantum Ring in ABA-Stacked Trilayer Graphene
Abdelhadi Belouad, Youness Zahidi, Ahmed Jellal +1
We present the solutions of the energy spectrum of charge carriers confined in quantum ring in ABA-stacked trilayer graphene subjected to a perpendicular magnetic field. The calcul…
Low energy Kbar N interactions and Faddeev calculation of the K- d scattering length in isospin and particle bases
A. Bahaoui, C. Fayard, T. Mizutani +1
$\Kbar N$ interactions are investigated {\it via} an effective non-linear chiral meson-baryon Lagrangian. The adjustable parameters are determined by a fitting procedure on the $K^…
