Experiments with arbitrary networks in time-multiplexed delay systems
Joseph D. Hart, Don C. Schmadel, Thomas E. Murphy +1
We report a new experimental approach using an optoelectronic feedback loop to investigate the dynamics of oscillators coupled on large complex networks with arbitrary topology. Ou…
Experimental observation of chimera and cluster states in a minimal globally coupled network
Joseph D. Hart, Kanika Bansal, Thomas E. Murphy +1
A "chimera state" is a dynamical pattern that occurs in a network of coupled identical oscillators when the symmetry of the oscillator population is broken into synchronous and asy…
Complete Characterization of Stability of Cluster Synchronization in Complex Dynamical Networks
Francesco Sorrentino, Louis M. Pecora, Aaron M. Hagerstrom +2
Synchronization is an important and prevalent phenomenon in natural and engineered systems. In many dynamical networks, the coupling is balanced or adjusted in order to admit globa…
Harvesting entropy and quantifying the transition from noise to chaos in a photon-counting feedback loop
Aaron M. Hagerstrom, Thomas E. Murphy, Rajarshi Roy
Some physical processes, including the intensity fluctuations of a chaotic laser, the detection of single photons, and the Brownian motion of a microscopic particle in a fluid are…
Symmetries, Cluster Synchronization, and Isolated Desynchronization in Complex Networks
Louis M. Pecora, Francesco Sorrentino, Aaron M. Hagerstrom +2
Synchronization is of central importance in power distribution, telecommunication, neuronal, and biological networks. Many networks are observed to produce patterns of synchronized…
Experimental Observations of Group Synchrony in a System of Chaotic Optoelectronic Oscillators
Caitlin R. S. Williams, Thomas E. Murphy, Rajarshi Roy +3
We experimentally demonstrate group synchrony in a network of four nonlinear optoelectronic oscillators with time-delayed coupling. We divide the nodes into two groups of two each,…
