Kinetic field theory: effects of modified gravity theories with screening mechanisms on non-linear cosmic density fluctuations
Alexander Oestreicher, Harshda Saxena, Niklas Reinhardt +3
In a mean-field approximation within Kinetic Field Theory, it is possible to derive an accurate analytic expression for the power spectrum of present-day non-linear cosmic density…

Cosmic Large-Scale Structure Formation from Newtonian Particle Dynamics
Tristan Daus, Elena Kozlikin
We present results for the cosmic non-linear density-fluctuation power spectrum based on the analytical formalism developed in [1] which allows us to study cosmic structure formati…

Field Theory Approach to Classical -Particle Systems In and Out of Equilibrium
Tristan Daus, Elena Kozlikin
We present an approach to solving the evolution of a classical -particle ensemble based on the path integral approach to classical mechanics. This formulation provides a perturb…
