Hubbard Model on the Honeycomb Lattice with an Indefinite Long-Range Interaction
Mohammad-Sadegh Vaezi, Davoud Nasr Esfahani
Several studies have emphasized the impact of long-range Coulomb interactions in lattice fermions, yet conventional Auxiliary Field Quantum Monte Carlo (QMC) methods face limitatio…
symmetry and electron-phonon interaction in two-dimensional crystalline systems
Mohammad Alidoosti, Davoud Nasr Esfahani, Reza Asgari
The coupling of electrons and phonons is governed wisely by the symmetry properties of the crystal structures. In particular, for two-dimensional (2D) systems, it has been suggeste…
Nonadiabatic transition at a band-touching point
Mohammad-Sadegh Vaezi, Davoud Nasr Esfahani
Low-energy Hamiltonians with a linear crossing in their energy dispersion (dubbed Dirac Hamiltonians) have recently been the subject of intense investigations. The linear dispersio…
Charge density wave and superconducting phase in monolayer InSe
Mohammad Alidoosti, Davoud Nasr Esfahani, Reza Asgari
In this paper, the completed investigation of a possible superconducting phase in monolayer indium selenide is determined using first-principles calculations for both the hole and…
Superconducting critical temperature of hole doped blue phosphorene
Davoud Nasr Esfahani, Reza Asgari
We theoretically explore the superconducting critical temperature of hole doped blue phosphorene. Implementing the density functional theory calculations, we show that for the hole…
Collapse of the low temperature insulating state in Cr-doped VO thin films
Pía Homm, Leander Dillemans, Mariela Menghini +10
We have grown epitaxial Cr-doped VO thin films with Cr concentrations between and on -AlO by oxygen-assisted molecular beam epitaxy. For the high…
An electric-field driven Mott metal-insulator transition in correlated thin films: an inhomogeneous dynamical mean-field theory approach
Petar Bakalov, Davoud Nasr Esfahani, Lucian Covaci +3
Simulations are carried out based on the dynamical mean-field theory (DMFT) in order to investigate the properties of correlated thin films for various values of the chemical poten…
Non-linear response to electric field in extended Hubbard models
D. Nasr Esfahani, L. Covaci, F. M. Peeters
The electric-field response of a one-dimensional ring of interacting fermions, where the interactions are described by the extended Hubbard model, is investigated. By using an accu…
Field effect on surface states in a doped Mott-Insulator thin film
D. Nasr Esfahani, L. Covaci, F. M. Peeters
Surface effects of a doped thin film made of a strongly correlated material are investigated both in the absence and presence of a perpendicular electric field. We use an inhomogen…
Electrical field induced shift of the Mott Metal-Insulator transition in thin films
D. Nasr Esfahani, L. Covaci, F. M. Peeters
The ground state properties of a paramagnetic Mott insulator are investigated in the presence of an external electrical field using the inhomogeneous Gutzwiller approximation for a…
