Modulational Instabilities and Domain Walls in Coupled Discrete Nonlinear Schrödinger Equations
Z. Rapti, A. Trombettoni, P. G. Kevrekidis +3
We consider a system of two discrete nonlinear Schrödinger equations, coupled by nonlinear and linear terms. For various physically relevant cases, we derive a modulational instabi…
Quantum logic operations and creation of entanglement in a scalable superconducting quantum computer with long-range constant interaction between qubits
G. P. Berman, A. R. Bishop, D. I. Kamenev +1
We consider a one-dimensional chain of many superconducting quantum interference devices (SQUIDs), serving as charge qubits. Each SQUID is coupled to its nearest neighbors through…
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…
Observable Signature of the Berezinskii-Kosterlitz-Thouless Transition in a Planar Lattice of Bose-Einstein Condensates
A. Trombettoni, A. Smerzi, P. Sodano
We investigate the possibility that Bose-Einstein condensates (BECs), loaded on a 2D optical lattice, undergo - at finite temperature - a Berezinskii-Kosterlitz-Thouless (BKT) tran…
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…
