SCL Seminar by Sebastian Eydam
SCL seminar of the Center for the Study of Complex Systems, will be held on Thursday, 28 September 2017 at 14:00 in the library reading room "Dr Dragan Popović" of the Institute of Physics Belgrade. The talk entitled
"Phase Oscillator Mode-Locking"
will be given by Sebastian Eydam (Weierstrass Institute for Applied Analysis and Stochastics, Berlin).
Abstract of the talk:
We investigate the dynamics of a Kuramoto-type system of globally coupled phase oscillators with equidistant natural frequencies and a coupling strength below the synchronization threshold. It turns out that in such cases one can observe a stable regime of sharp pulses in the mean field amplitude with a pulsation frequency given by the spacing of the natural frequencies. This resembles a process known as mode-locking in lasers and relies on the emergence of a phase relation induced by the nonlinear coupling. We explain the role of the first and second harmonic in the phase-interaction function for the stability of the pulsations. Further we address the issue of transient dynamics and the connection between extensive chaos and mode-locked solutions.
