Dissipative Josephson effect in coupled nanolasers

dissipative coupled cavities

We investigate the mean-field dynamics of a system of interacting photons in an array of coupled cavities in the presence of dissipation and disorder. We follow the evolution of an initially prepared Fock state, and show how the interplay between dissipation and disorder affects the coherence properties of the cavity emission, and show that these properties can be used as signatures of the many...

Dissipative enhancement of the supercurrent in Tl2Ba2CaCu2O8 intrinsic Josephson junctions.

We have measured dissipation-induced localization of the reaction coordinate for a metastable-state decay process in a model system with moderate damping. Specifically, the supercurrent in an array of Tl2Ba2CaCu2O8 intrinsic Josephson junctions is larger when all the junctions are in the zero-voltage state than when one or more junctions are in the voltage state since the dissipation is larger ...

Unfolding isochronicity in weakly dissipative coupled oscillators

We consider the dynamics of networks of oscillators that are weakly dissipative perturbations of identical Hamiltonian oscillators with weak coupling. Suppose the Hamilto-nian oscillators have angular frequency !() when their energy is. We address the problem of what happens in a neighbourhood of where d!=dd = 0; we refer to this as a point of isochronicity for the oscillators. If the coupling ...

Dissipative Topological Defects in Coupled Laser Networks

Topologically protected defects have been observed and studied in a wide range of fields, such as cosmology, spin systems, cold atoms and optics as they are quenched across a phase transition into an ordered state. Revealing their origin and control is becoming increasingly important field of research, as they limit the coherence of the system and its ability to approach a fully ordered state. ...
