Nonlinear and Complex Physics Group
The Nonlinear and Complex Physics Group aims to stimulate interest and advance progress in the study of nonlinear processes and complexity in the physical sciences and its application to other disciplines.
Nonlinear problems are ubiquitous in nature yet there are no general principles to guide our understanding of observed complex behaviour. However, modern developments in nonlinear dynamics coupled with scaling and universality arguments have helped us make progress with problems ranging in scale from the quantum to the astrophysical. The topics covered in these strongly nonlinear phenomena range from solitons and vortices in optics, networks and disease propagation in biology, to turbulence and pattern formation in classical physics. Complexity is concerned with the central nature of change and evolution and places emphasis on the role of fluctuations and noise in self-organisation. In many of these areas, progress is most often made using an interdisciplinary approach often coupling experiment with theory. Drawing connections between many of these areas has its roots in statistical physics and critical phenomena and the approach is now finding application in emerging areas such as soft matter, complexity, biophysics.and indeed evolutionary biology and related fields.
