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…
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…
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: general formalism and linear structure growth from Newtonian particle dynamics
Robert Lilow, Felix Fabis, Elena Kozlikin +2
In earlier work, we have developed a nonequilibrium statistical field theory description of cosmic structure formation, dubbed Kinetic Field Theory (KFT), which is based on the Ham…
Analytic calculation of the non-linear cosmic density-fluctuation power spectrum in the Born approximation
Matthias Bartelmann, Felix Fabis, Sara Konrad +4
We derive a non-perturbative, closed, analytic equation for the non-linear power spectrum of cosmic density fluctuations. This result is based on our kinetic field theory (KFT) of…
Kinetic Field Theory: Effects of momentum correlations on the cosmic density-fluctuation power spectrum
Matthias Bartelmann, Felix Fabis, Elena Kozlikin +3
In earlier work, we have developed a Kinetic Field Theory (KFT) for cosmological structure formation and showed that the non-linear density-fluctuation power spectrum known from nu…
Non-equilibrium statistical field theory for classical particles: Non-linear structure evolution with first-order interaction
Matthias Bartelmann, Felix Fabis, Daniel Berg +3
We calculate the power spectrum of density fluctuations in the statistical non-equilibrium field theory for classical, microscopic degrees of freedom to first order in the interact…
Non-equilibrium statistical field theory for classical particles: Linear and mildly non-linear evolution of cosmological density power spectra
Matthias Bartelmann, Felix Fabis, Daniel Berg +3
We use the non-equlibrium statistical field theory for classical particles, recently developed by Mazenko and Das and Mazenko, together with the free generating functional we have…
