Conditions for magnetically induced singlet d-wave superconductivity on the square lattice
S. R. Hassan, B. Davoudi, B. Kyung +1
It is expected that at weak to intermediate coupling, d-wave superconductivity can be induced by antiferromagnetic fluctuations. However, one needs to clarify the role of Fermi sur…
Kondo lattice model at half-filling
R. Nourafkan, N. Nafari
The single- and two-channel Kondo lattice model consisting of localized spins interacting antiferromagnetically with the itinerent electrons, are studied using dynamical mean field…
Ground-state properties of the one dimensional electron liquid
R. Asgari
We present a theory of the pair distribution function and many-body effective electron-electron interaction for one dimensional (1D) electron liquid. Our approach involves t…
Non-Perturbative Treatment of Charge and Spin Fluctuations in the Two-Dimensional Extended Hubbard Model: Extended Two-Particle Self-Consistent Approach
B. Davoudi, A. -M. S. Tremblay
We study the spin and charge fluctuations of the extended Hubbard model (EHM) with on-site interaction U and first neighbor interaction V on the two-dimensional square lattice in t…
Chirality and Correlations in Graphene
Yafis Barlas, T. Pereg-Barnea, Marco Polini +2
Graphene is described at low-energy by a massless Dirac equation whose eigenstates have definite chirality. We show that the tendency of Coulomb interactions in lightly doped graph…
