[institut] SCL Seminar: Sebastian Eydam, Thursday, 28 September, 14:00

[Igor Franovic]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study 
of Complex Systems, which 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 is provided 
below.

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.

Best regards,
Dr Igor Franović
