Structure formation with Kinetic Field Theory (joint seminar with MPIK)
The formation of structure is a global phenomenon in physics that can be found on all scales. Understanding the mechanisms behind structure formation on a fundamental level requires a theory that is abstract enough to be applicable to a great variety of systems. Due to the non-linearities generally involved in the formation and evolution of structures, the theoretical treatment has proven a formidable task not only in cosmology but also for laboratory systems. In this seminar I will give an introduction to Kinetic Field Theory (KFT), a novel analytical approach to structure formation in classical many-body systems based on a microscopic, non-equilibrium, statistical field theory. The applicability of KFT is not restricted to any particular setting and offers a great amount of freedom in choosing the fundamental laws that enter into the description of structure formation, such as the equations of motion, the particle interaction potential and the initial conditions. I will, furthermore, discuss two applications of the theory: (1) the application to cosmic large-scale structure formation and (2) the application to correlated laboratory gases.
