A first comparison of Kinetic Field Theory with Eulerian Standard Perturbation Theory
Elena Kozlikin, Robert Lilow, Felix Fabis +1
We present a detailed comparison of the newly developed particle-based Kinetic Field Theory framework for cosmic large-scale structure formation with the established formalism of E…
Kinetic field theory: Non-linear cosmic power spectra in the mean-field approximation
Matthias Bartelmann, Johannes Dombrowski, Sara Konrad +5
We use the recently developed Kinetic Field Theory (KFT) for cosmic structure formation to show how non-linear power spectra for cosmic density fluctuations can be calculated in a…
Cosmic Structure Formation with Kinetic Field Theory
Matthias Bartelmann, Elena Kozlikin, Robert Lilow +7
Kinetic Field Theory (KFT) is a statistical field theory for an ensemble of point-like classical particles in or out of equilibrium. We review its application to cosmological struc…
Resummed Kinetic Field Theory: Using Mesoscopic Particle Hydrodynamics to Describe Baryonic Matter in a Cosmological Framework
Daniel Geiss, Robert Lilow, Felix Fabis +1
Recently, Bartelmann et al. presented a 'Kinetic Field Theory' (KFT) formalism to tackle the difficulties of large scale structure formation. In this approach, the dynamics of a no…
A Model for Hydrodynamics in Kinetic Field Theory
C. Viermann, J. T. Schneider, R. Lilow +4
In this work, we introduce an effective model for both ideal and viscous fluid dynamics within the framework of kinetic field theory (KFT). The main application we have in mind is…
Resummed Kinetic Field Theory: general formalism and linear structure growth from Newtonian particle dynamics
