Dark matter vorticity and velocity dispersion from truncated Dyson$\unicode{x2013}$Schwinger equations
Alaric Erschfeld, Stefan Floerchinger
Large-scale structure formation is studied in a kinetic theory approach, extending the standard perfect pressureless fluid description for dark matter by including the velocity dis…
Cosmological functional renormalisation group, extended Galilean invariance and the sweeping effect
Alaric Erschfeld, Stefan Floerchinger
The functional renormalisation group is employed to study the non-linear regime of late-time cosmic structure formation. This framework naturally allows for non-perturbative approx…
The dark matter bispectrum from effective viscosity and one-particle irreducible vertices
Stefan Floerchinger, Mathias Garny, Aris Katsis +2
Dark matter evolution during the process of cosmological structure formation can be described in terms of a one-particle irreducible effective action at a characteristic scale $k_m…
Evolution of dark matter velocity dispersion
Alaric Erschfeld, Stefan Floerchinger
Cosmological perturbation theory for the late Universe dominated by dark matter is extended beyond the perfect fluid approximation by taking the dark matter velocity dispersion ten…
Effective description of dark matter as a viscous fluid
S. Floerchinger, M. Garny, N. Tetradis +1
Treating dark matter at large scales as an effectively viscous fluid provides an improved framework for the calculation of the density and velocity power spectra compared to the st…
Renormalization-group flow of the effective action of cosmological large-scale structures
Stefan Floerchinger, Mathias Garny, Nikolaos Tetradis +1
Following an approach of Matarrese and Pietroni, we derive the functional renormalization group (RG) flow of the effective action of cosmological large-scale structures. Perturbati…
