Antiferromagnetic Chern insulator in centrosymmetric systems
Morad Ebrahimkhas, Götz S. Uhrig, Walter Hofstetter +1
An antiferromagnetic Chern insulator (AFCI) can exist if the effect of the time-reversal transformation on the electronic state cannot be compensated by a space group operation. Th…
A New Black Hole Solution In Dilaton Gravity Inspired By Power-Law Electrodynamics
Younes Younesizadeh, Amir A. Ahmad, Ali Hassan Ahmed +2
In this work, a new class of slowly rotating black hole solutions in dilaton gravity has been obtained where dilaton field is coupled with nonlinear Maxwell invariant. The backgrou…
Lattice symmetry and emergence of antiferromagnetic quantum Hall states
Morad Ebrahimkhas, Mohsen Hafez-Torbati, Walter Hofstetter
Strong local interaction in systems with non-trivial topological bands can stabilize quantum states such as magnetic topological insulators. We investigate the influence of the lat…
Quantum Phase transition in the two dimensional ionic-Hubbard model
A. Shahbazy, M. Ebrahimkhas
We employ the dynamical mean field approximation to study the effects of ionic potential () on the square lattice Hubbard model. At half-filling when the staggered potential ($Δ…
Effects of correlations on honeycomb lattice in ionic-Hubbard Model
M. Ebrahimkhas, Z. Drezhegrighash, E. Soltani
In a honeycomb lattice the symmetry has been broken by adding an ionic potential and a single-particle gap was generated in the spectrum. We have employed the iterative perturbatio…
Analysis the neutral triplet collective mode in honeycomb lattice: without one-cone approximation
M. Ebrahimkhas
In this research has been studied the possibility of existence the neutral triplet collective mode in undoped graphene and graphite without one-cone approximation. This work tries…
