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 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…
