Mean-field theory for Bose-Hubbard Model under a magnetic field
M. O. Oktel, M. Nita, B. Tanatar
We consider the superfluid-insulator transition for cold bosons under an effective magnetic field. We investigate how the applied magnetic field affects the Mott transition within…
Asymmetric localization in disordered Landau bands
A. Aldea, M. Nita
We show that due to the Landau band mixing the eigenstate localization within the disordered bands get an asymmetric structure: the degree of localization increases in the lower pa…
Net current generation in a 1D quantum ring at zero magnetic field
Sigridur Sif Gylfadottir, Marian Nita, Vidar Gudmundsson +1
We study a non-adiabatic excitation of an electron system in a 1D quantum ring radiated by a short THz pulse. The response of two models, a continuous and discrete, is explored. By…
Spin magnetization of strongly correlated electron gas confined in a two-dimensional finite lattice
M. Nita, V. Dinu, A. Aldea +1
The influence of disorder and interaction on the ground state polarization of the two-dimensional (2D) correlated electron gas is studied by numerical investigations of unrestricte…
