Time evolution of density matrices as a theory of random surfaces
Carlo Pagani, Martin Reuter
In the operatorial formulation of quantum statistics, the time evolution of density matrices is governed by von Neumann's equation. Within the phase space formulation of quantum me…
Operator product expansion coefficients from the nonperturbative functional renormalization group
Félix Rose, Carlo Pagani, Nicolas Dupuis
Using the nonperturbative functional renormalization group (FRG) within the Blaizot-Méndez-Galain-Wschebor approximation, we compute the operator product expansion (OPE) coefficien…
Eulerian spatio-temporal correlations in passive scalar turbulence
Anastasiia Gorbunova, Carlo Pagani, Guilaume Balarac +2
We study the spatio-temporal two-point correlation function of passively advected scalar fields in the inertial-convective range in three dimensions by means of numerical simulatio…
Spatio-temporal correlation functions in scalar turbulence from functional renormalization group
Carlo Pagani, Léonie Canet
We provide the leading behavior at large wavenumbers of the two-point correlation function of a scalar field passively advected by a turbulent flow. We first consider the Kraichnan…
Operator product expansion coefficients in the exact renormalization group formalism
C. Pagani, H. Sonoda
We study how to compute the operator product expansion coefficients in the exact renormalization group formalism. After discussing possible strategies, we consider some examples ex…
Fractal geometry of higher derivative gravity
Maximilian Becker, Carlo Pagani, Omar Zanusso
We determine the scaling properties of geometric operators such as lengths, areas, and volumes in models of higher derivative quantum gravity by renormalizing appropriate composite…
