Jakub Sawicki is a professional musician and physicist. His research is combining aspects of both fields. He studied music at Listaháskóli Islands University and University of Arts Berlin. Apart from his position as organist at Berlin Cathedral, Jakub Sawicki has deepened his studies of organ improvisation. He has engagements as choir and orchestra conductor and teaches improvisation at University of Arts Berlin. At the same time, he has continued his scientific research and received the Dr. rer. nat. degree from the Technical University Berlin. His research interests include synchronization phenomena in music, nonlinear delay differential equations, modeling of complex systems and neural dynamics.

• Introduction.- Complex Systems.- Part 1: Single-Layer Systems.- Two Coupled Oscillators.- Chimeras in Net Works Without Delay.- Interplay Of Delay and Fractal Topology.- Part 2: Multilayer Systems.- Partial Synchronization in 2-Community Networks.- Multiplex Networks.- Conclusion.
