Dynamical renormalization group for mode-coupling field theories with solenoidal constraint
Andrea Cavagna, Luca di Carlo, Irene Giardina +3
The recent inflow of empirical data about the collective behaviour of strongly correlated biological systems has brought field theory and the renormalization group into the biophys…
Equilibrium to off-equilibrium crossover in homogeneous active matter
Andrea Cavagna, Luca Di Carlo, Irene Giardina +2
We study the crossover between equilibrium and off-equilibrium dynamical universality classes in the Vicsek model near its ordering transition. Starting from the incompressible hyd…
Renormalization group crossover in the critical dynamics of field theories with mode coupling terms
Andrea Cavagna, Luca Di Carlo, Irene Giardina +3
Motivated by the collective behaviour of biological swarms, we study the critical dynamics of field theories with coupling between order parameter and conjugate momentum in the pre…
Dynamical renormalization group approach to the collective behaviour of swarms
Andrea Cavagna, Luca Di Carlo, Irene Giardina +3
We study the critical behaviour of a model with non-dissipative couplings aimed at describing the collective behaviour of natural swarms, using the dynamical renormalization group.…
