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…
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…
