Critical aging and relaxation dynamics in long-range systems
Valerio Pagni, Friederike Ihssen, Nicolò Defenu
We study the dynamical scaling of long-range models after a sudden quench to the critical temperature, using the functional renormalization group approach. We chara…

One-dimensional long-range Ising model: two (almost) equivalent approximations
Valerio Pagni, Guido Giachetti, Andrea Trombettoni +1
We investigate the critical behavior of the one-dimensional Ising model with long-range interactions using the functional renormalization group in the local potential approximation…

Nonperturbative treatment of a quenched Langevin field theory
Friederike Ihssen, Valerio Pagni, Jamir Marino +2
We present a novel approach within the functional renormalization group framework for computing critical exponents that characterize the time evolution of out-of-equilibrium many-b…
