Surface Polaron Formation in the Holstein model
Reza Nourafkan, Massimo Capone, Nasser Nafari
The effect of a solid-vacuum interface on the properties of a strongly coupled electron-phonon system is analyzed using dynamical mean-field theory to solve the Holstein model in a…
Single bipolaronic Transition in Jahn-Teller Model
Reza Nourafkan, Massimo Capone, Nasser Nafari
We investigate the bipolaronic crossover and the pairing transition for a two-orbital model with Jahn-Teller coupling to a two-fold degenerate phonon mode. The evolution from weak…
The calculation of the effective interaction parameter in LDA+U method by linear response approach for Fe(OH)2
Mansoureh Pashangpour, Khadijeh Imani, Amir Abbas Sabouri-Dodaran +1
In this paper we have investigated the electronic properties of Fe(OH)2 hydroxide by using the LSDA+U as well as the generalized gradient approximation. Our calculations for the ir…
Phase diagram of Holstein-Kondo lattice model at half-filling
Reza Nourafkan, Nasser Nafari
We study the Kondo lattice model which is modified by the Holstein term, involving both the Kondo exchange coupling and the electron-phonon coupling constants, characterized by …
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…
Roughness of undoped graphene and its short-range induced gauge field
N. Abedpour, M. Neek-Amal, Reza Asgari +3
We present both numerical and analytical study of graphene roughness with a crystal structure including atoms. The roughness can effectively result in a random gau…
