Topological pumping in the one-dimensional Bose-Hubbard model
Davide Rossini, Marco Gibertini, Vittorio Giovannetti +1
By means of time-dependent density matrix renormalization group calculations we study topological quantum pumping in a strongly interacting system. The system under consideration i…
Scattering theory of topological invariants in nodal superconductors
J. P. Dahlhaus, M. Gibertini, C. W. J. Beenakker
Time-reversal invariant superconductors having nodes of vanishing excitation gap support zero-energy boundary states with topological protection. Existing expressions for the topol…
Two-dimensional Mott-Hubbard electrons in an artificial honeycomb lattice
A. Singha, M. Gibertini, B. Karmakar +8
Electrons in artificial lattices enable explorations of the impact of repulsive Coulomb interactions in a tunable system. We have trapped two-dimensional electrons belonging to a g…
Engineering artificial graphene in a two-dimensional electron gas
M. Gibertini, A. Singha, V. Pellegrini +5
At low energy, electrons in doped graphene sheets behave like massless Dirac fermions with a Fermi velocity which does not depend on carrier density. Here we show that modulating a…
