On Defect-Mediated Transitions in Bosonic Planar Lattices
A. Trombettoni, A. Smerzi, P. Sodano
We discuss the finite-temperature properties of Bose-Einstein condensates loaded on a 2D optical lattice. In an experimentally attainable range of parameters the system is describe…
Topology Induced Spatial Bose-Einstein Condensation for Bosons on Star-Shaped Optical Networks
I. Brunelli, G. Giusiano, F. P. Mancini +2
New coherent states may be induced by pertinently engineering the topology of a network. As an example, we consider the properties of non-interacting bosons on a star network, whic…
Topology Induced Macroscopic Quantum Coherence in Josephson Junction Networks
G. Giusiano, F. P. Mancini, P. Sodano +1
We argue that Josephson junction networks may be engineered to allow for the emergence of new and robust quantum coherent states. We provide a rather intuitive argument showing how…
On the Phase Diagram of Josephson Junction Arrays with Offset Charges
F. P. Mancini, P. Sodano, A. Trombettoni
We study the effects of external offset charges on the phase diagram of Josephson junction arrays. Using the path integral approach, we provide a pedagogical derivation of the equa…
Self-Consistent Mean-Field Theory for Frustrated Josephson Junction Arrays
F. P. Mancini, P. Sodano, A. Trombettoni
We review the self-consistent mean-field theory for charge-frustrated Josephson junction arrays. Using <cos(ϕ)> (ϕis the phase of the superconducting wavefunction) as order paramet…
A Novel Mechanism for Superfluidity Breakdown in Weakly Coupled Bose-Einstein Condensates
F. S. Cataliotti, L. Fallani, F. Ferlaino +7
This paper has been withdrawn by the authors. The authors have now written two separate papers, one theoretical (A. Smerzi, A. Trombettoni, P. G. Kevrekidis, and A. R. Bishop Phys.…
