Charge-fluctuations in lightly hole-doped cuprates: effect of vertex corrections
R. Nourafkan, M. Côté, A. - M. S. Tremblay
Identification of the electronic state that appears upon doping a Mott insulator is important to understand the physics of cuprate high-temperature superconductors. Recent scanning…
Effect of nonsymmorphic space group on correlation functions in iron-based superconductors
R. Nourafkan, A. -M. S. Tremblay
The orbital basis is natural when one needs to calculate the effect of local interactions or to unravel the role of orbital physics in the response to external probes. In systems w…
Electric polarization of SrBaMnO: a multiferroic Mott insulator
R. Nourafkan, G. Kotliar, A. -M. S. Tremblay
Ab initio calculations of the electric polarization of correlation-driven insulating materials, namely Mott insulators, have not been possible so far. Using a combination of densit…
Orbital magnetization of correlated electrons with arbitrary band topology
R. Nourafkan, G. Kotliar, A. -M. S. Tremblay
Spin-orbit coupling introduces chirality into electronic structure. This can have profound effects on the magnetization induced by orbital motion of electrons. Here we derive a for…
Electric polarization in correlated insulators
R. Nourafkan, G. Kotliar
We derive a formula for the electric polarization of interacting insulators, expressed in terms of the full Green's and vertex functions. We exemplify this method in the half-fille…
Model of the electron-phonon interaction and optical conductivity of BaKBiO superconductors
R. Nourafkan, F. Marsiglio, G. Kotliar
We investigate the physical properties of the BaKBiO compounds with a focus on the optical properties. Results from the simple Holstein model, describing a single b…
