Extended Bose Hubbard model of interacting bosonic atoms in optical lattices: from superfluidity to density waves
G. Mazzarella, S. M. Giampaolo, F. Illuminati
For systems of interacting, ultracold spin-zero neutral bosonic atoms, harmonically trapped and subject to an optical lattice potential, we derive an Extended Bose Hubbard (EBH) mo…
Massive Quantum Memories by Periodically Inverted Dynamic Evolutions
S. M. Giampaolo, F. Illuminati, A. Di Lisi +1
We introduce a general scheme to realize perfect quantum state reconstruction and storage in systems of interacting qubits. This novel approach is based on the idea of controlling…
Engineering massive quantum memories by topologically time-modulated spin rings
S. M. Giampaolo, F. Illuminati, A. Di Lisi +1
We introduce a general scheme to realize perfect storage of quantum information in systems of interacting qubits. This novel approach is based on {\it global} external controls of…
Influence of trapping potentials on the phase diagram of bosonic atoms in optical lattices
S. M. Giampaolo, F. Illuminati, G. Mazzarella +1
We study the effect of external trapping potentials on the phase diagram of bosonic atoms in optical lattices. We introduce a generalized Bose-Hubbard Hamiltonian that includes the…
A new expansion around mean field for the quantum Ising model
F. De Pasquale, S. M. Giampaolo
We show that an high temperature expansion at fixed order parameter can be derived for the quantum Ising model. The basic point is to consider a statistical generating functional a…
Local quantum coherence and superfluidity
F. de Pasquale, S. M. Giampaolo
We consider a model of bosons on a regular lattice with a kinetic energy due to hopping among sites and a potential energy due to strong on site interaction. A superfluid phase is…
