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…
