Description
Finding an analytic theory to describe non-linear cosmic structure formation has proven to be a challenge that is yet to be solved in a satisfactory way.
What makes the matter so difficult is that we are looking at a system of classical particles far from equilibrium with long-range interactions.
One theory that has been developed in recent years to tackle such systems is Kinetic Field Theory (KFT), which uses the microscopic phase-space dynamics of individual particles to predict collective quantities of the entire system, such as correlation functions.
In contrast to more established analytical methods such as Eulerian- or Lagrangian perturbation theory KFT, in principle, offers a complete description of the system and does not suffer from inconsistencies arising due to the crossing particle streams.
I want to present recent progress in the description of particle interactions in the framework of KFT and how this affects our predictions for measurable quantities such as the non-linear dark matter power spectrum.
