Spatio-temporal pattern formation in time-delayed optical systems — •Svetlana Gurevich — Institute for Theoretical Physics, University of Münster, Germany

Control and engineering of complex spatio-temporal patterns in high-dimensional non-equilibrium systems has evolved as one of the central issues in applied nonlinear science. However, real-world complex systems can be strongly influenced by time delays due to unavoidable finite signal propagation speeds and time-delayed dynamical systems have proven to be a fertile framework for the modeling of nonlinear phenomena. Nonlinear laser dynamics is one of the fields where time-delayed system are frequently employed to model the arising complex dynamics. In this talk, we will explore time-delayed models to describe the behavior of ultrashort pulses in optical micro-cavities, highlighting their potential for the formation of spatio-temporal structures.
