[Chaos and Network Synchronization]
A lecture by
Lucas Illing
Candidate for the position in Physics

Time-delayed coupling and self-feedback occurs in many systems and is particularly important at high speeds, where the time it takes signals to propagate through device components is comparable to the time scale of the signal fluctuations. A fascinating feature of systems with delay is that even seemingly simple devices can show exceedingly complex dynamics such as chaos.  I will talk about the generation of high-speed chaos using optoelectronic time-delayed feedback oscillators and discuss a particularly intriguing form of collective behavior that arises when several such oscillators are coupled to form a network. Under certain conditions the entire network will oscillate in synchrony, in spite of the signal propagation delays in the coupling links.
