Quantum phases and dynamics of Bosonic lattice systems

Bosonic fluids formed by one or more ultracold atomic components and in the presence of trapping potentials exhibit a quite rich phenomenology.This is particularly true in the presence of strongly nonlinear interactions and in lattices with complex geometries.

We investigate:

• instability effects, macroscopic quantum oscillations, transitions to localized states and supercurrents.
• dynamical phase transitions at the crossover between classical and quantum regimes.
• miscibility, entanglement properties and non-zero temperature effects in the quantum phases of bosonic and fermionic mixtures characterized by space separation.
• frustration and long-range interaction in bosonic lattice systems
