Density-Functional Theory of Graphene Sheets
Marco Polini, Andrea Tomadin, Reza Asgari +1
We outline a Kohn-Sham-Dirac density-functional-theory (DFT) scheme for graphene sheets that treats slowly-varying inhomogeneous external potentials and electron-electron interacti…
Many-body Landau-Zener tunneling in the Bose-Hubbard model
Andrea Tomadin, Riccardo Mannella, Sandro Wimberger
We study a model for ultracold, spinless atoms in quasi-one dimensional optical lattices and subjected to a tunable tilting force. Statistical tests are employed to quantitatively…
Nonequilibrium pairing instability in ultracold Fermi gases with population imbalance
Andrea Tomadin, Marco Polini, M. P. Tosi +1
We present detailed numerical and analytical investigations of the nonequilibrium dynamics of spin-polarized ultracold Fermi gases following a sudden switching-on of the atom-atom…
