Vorlesung: (Beginn 14.10.)
Mi 10:15-11:45 (EW 731)

Für Studierende der Physik (Master und Diplom-Hauptstudium), des Masterstudiengangs Computational Neuroscience und interessierte Mitglieder des SFB 910.

When attending this course 3 credit points within the ECTS system can be obtained. The course will be given in English.

Zusammen mit der Lehrveranstaltung LV 3232 L 152 „Theoretische Physik VI (Vertiefung): Nichtgleichgewichtsstatistik“ kann diese Vorlesung zu einem physikalischen Wahlpflichtmodul (grundlagenorientierte Studienrichtung) mit 12 ECTS kombiniert werden.

The lectures cover major ideas of complex network theory, with emphasis on nonlinear dynamics and applications in real-world systems. A focus is put on characterization of emergent collective behavior when the network nodes are coupled over various configurations, including the Kuramoto model of coupled phase oscillators and coupled chaotic maps. Conditions for different types of synchronization and clustering will be derived with combination of analytical methods and numerical simulations. The main attention will be paid to chimera states as one of the most fascinating recent discoveries in nonlinear science, illuminating self-organized spatial coexistence of synchronization and desynchronization. Experimental evidence of chimera states will be presented for such fields as neuroscience, chemistry, optics, fluid dynamics, and mechanical systems.

More specifically, the following topics will be discussed in the lectures:

• Synchronization in complex networks, theory and application
• Nonlinear dynamics, bifurcations and chaos
• Kuramoto model: collective dynamics and phase chaos
• Chaotic synchronization, riddling and blowout bifurcations
• Chimera states as a new paradigm of network science
• Different types of chimera states in Kuramoto, FitzHugh-Nagumo and coupled map models
• Kuramoto model with inertia, solitary states and spatial chaos
• Self-propelled chimeras in the Vicsek model
• Chimera states in delayed-feedback systems
• Chimera states in 2 and 3 spatial dimensions: spiral and scroll wave chimeras
• Experimental evidence of chimera states
