An Ising machine based on networks of subharmonic electrical resonators
L. Q. English, A. V. Zampetaki, K. P. Kalinin +2
We explore a case example of networks of classical electronic oscillators evolving towards the solution of complex optimization problems. We show that when driven into subharmonic…
Experimental and numerical observation of dark and bright discrete solitons in the band-gap of a diatomic-like electrical lattice
F. Palmero, L. Q. English, Xuan-Lin Chen +3
We observe dark and bright intrinsic localized modes (ILMs) or discrete breathers (DB) experimentally and numerically in a diatomic-like electrical lattice. The generation of dark…
Impulse-induced localized nonlinear modes in an electrical lattice
F. Palmero, J. Cuevas-Maraver, L. Q. English +1
Intrinsic localized modes, also called discrete breathers, can exist under certain conditions in one-dimensional nonlinear electrical lattices driven by external harmonic excitatio…
The emergence and analysis of Kuramoto-Sakaguchi-like models as an effective description for the dynamics of coupled Wien-bridge oscillators
L. Q. English, David Mertens, Saidou Abdoulkary +3
We derive the Kuramoto-Sakaguchi model from the basic circuit equations governing two coupled Wien-bridge oscillators. A Wien-bridge oscillator is a particular realization of a tun…
Multifrequency and edge breathers in the discrete sine-Gordon system via subharmonic driving: theory, computation and experiment
F. Palmero, J. Han, L. Q. English +2
We consider a chain of torsionally-coupled, planar pendula shaken horizontally by an external sinusoidal driver. It has been known that in such a system, theoretically modeled by t…
Discrete breathers in a forced-damped array of coupled pendula: Modeling, Computation and Experiment
J. Cuevas, L. Q English, P. G. Kevrekidis +1
In this work, we present a mechanical example of an experimental realization of a stability reversal between on-site and inter-site centered localized modes. A corresponding realiz…
