We present the design of a superconducting qubit that has circulating currents of opposite
sign as its two states. The circuit consists of three nanoscale aluminum Josephson junctions …

Synchronization over networks depends strongly on the structure of the coupling between
the oscillators. When the coupling presents certain regularities, the dynamics can be coarse …

The analysis of complex networks has so far revolved mainly around the role of nodes and
communities of nodes. However, the dynamics of interconnected systems is often focalized …

We study the temporal dynamics of the generalized repressilator, a network of coupled
repressing genes arranged in a directed ring topology, and give analytical conditions for the …

The phenomenon of intrinsic localization in discrete nonlinear extended systems, ie the
(generic) existence of discrete breathers, is shown to be not restricted to periodic solutions …

We study the dynamics of one-dimensional arrays of Josephson junctions connected in
parallel by superconducting wires. These arrays are model systems for the discrete, damped …

We study the existence and uniqueness of single-wave-form solutions for series arrays of N
Josephson junctions coupled through general RLC loads. Our method recasts the …

We report on the experimental generation of discrete breather states (intrinsic localized
modes) in frustrated Josephson arrays. Our experiments indicate the formation of discrete …

We present analytical and numerical studies of pinned superconducting states of open-
ended Josephson ladder arrays, neglecting inductances but taking edge effects into …

Electromagnetic waves which propagate along a Josephson junction ladder are shown to
manifest themselves by resonant steps in the current-voltage characteristics. We report on …
