Talk Title:  “Turbulence and Self-Organization in Complex Systems from Astrophysical to Biophysical Scales”


Turbulence is a fundamental and ubiquitous phenomenon in nature, occurring from astrophysical to biophysical scales. At the same time, it is widely recognized as one of the key unsolved problems in modern physics, representing a paradigmatic example of self-organization far from thermodynamic equilibrium. While in the past, most theoretical work in this area has been devoted to Navier-Stokes flows, there is now a growing awareness of the need to extend the research focus to systems with more general patterns of energy injection and dissipation. This includes astrophysical and laboratory plasmas, as well as active systems consisting of self-propelled particles. Regarding plasmas, an impressive combination of new experimental and observational data, new theoretical concepts, and new computational capabilities have and will become available. Thus, we are facing a unique window of opportunity to push the boundaries of our grasp of turbulence. Interestingly, certain insights and concepts developed in this area of physics can be transferred to others, like biophysics, allowing for cross-fertilization and the development of a unifying view on seemingly disparate fields of science.
