"Networks of Coupled Oscillators in the Lab"

by Joseph Hart

Advisor:  Professors Rajarshi Roy and Thomas Murphy

Friday, May 11, 2018 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Complex networks of coupled oscillators are physically and biologically relevant systems that can display incredibly rich dynamical behaviors. Despite great theoretical advances in our understanding of coupled oscillator networks, it has proven difficult to design experiments that permit the study of dynamics on large networks with arbitrary topology. In this talk, I will explain how optoelectronics can provide a versatile experimental platform to study dynamics on networks of coupled oscillators. I will describe small networks of time-delayed feedback oscillators, networks implemented on a liquid crystal spatial light modulator system, and an optoelectronic implementation of a new general approach that allows for the investigation of large networks of truly identical nodes with arbitrary topology. I will discuss how we have used these systems to experimentally study global synchronization, cluster synchronization, and chimera states in coupled oscillator networks.
