Quantum capacitance of double-layer graphene
Fariborz Parhizgar, Alireza Qaiumzadeh, Reza Asgari
We study the ground-state properties of a double layer graphene system with the Coulomb interlayer electron-electron interaction modeled within the random phase approximation. We f…
Spin polarization dependence of quasiparticle properties in graphene
Alireza Qaiumzadeh, Kh. Jahanbani, Reza Asgari
We address spin polarization dependence of graphene's Fermi liquid properties quantitatively using a microscopic Random Phase Approximation theory in an interacting spin-polarized…
Conductance of bilayer graphene in the presence of a magnetic field: Effects of disorder
H. Hatami, N. Abedpour, A. Qaiumzadeh +1
We investigate the electronic transport properties of unbiased and biased bilayer graphene nanoribbon in n-p and n-n junctions subject to a perpendicular magnetic field. Using the…
The effect of sublattice symmetry breaking on the electronic properties of a doped graphene
Alireza Qaiumzadeh, Reza Asgari
Motivated by a number of recent experimental studies, we have carried out the microscopic calculation of the quasiparticle self-energy and spectral function in a doped graphene whe…
Stoner ferromagnetic phase of a graphene in the presence of an in-plane magnetic field
A. Qaiumzadeh, Reza Asgari
We study the effects of an in-plane magnetic field on the ground state properties of both gapless and gapped graphene sheets within Random Phase Approximation. The critical magneti…
Dynamical properties of quasiparticles in a gapped graphene sheet
A. Qaiumzadeh, F. K. Joibari, Reza Asgari
We present numerical calculations of the impact of charge carriers-carriers interactions on the dynamical properties of quasiparticles such as renormalized velocity and quasipartic…
