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…

Variational principle for theories with dissipation from analytic continuation
Stefan Floerchinger
The analytic continuation from the Euclidean domain to real space of the one-particle irreducible quantum effective action is discussed in the context of generalized local equilibr…
