Resummed Kinetic Field Theory: a model of coupled baryonic and dark matter
Daniel Geiss, Ivan Kostyuk, Robert Lilow +1
We present a new analytical description of cosmic structure formation in a mixture of dark and baryonic matter, using the framework of Kinetic Field Theory (KFT) -- a statistical f…
Brownian Thermometry Beyond Equilibrium
Daniel Geiss, Klaus Kroy
Since Albert Einstein's seminal 1905-paper on Brownian motion, the temperature of fluids and gases of known viscosity can be deduced from observations of the fluctuations of small…
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…
Brownian Molecules Formed by Delayed Harmonic Interactions
Daniel Geiss, Klaus Kroy, Viktor Holubec
A time-delayed response of individual living organisms to information exchanged within flocks or swarms leads to the emergence of complex collective behaviors. A recent experimenta…
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…
