In the last few years the derivative expansion of the nonperturbative renormalization group
has proven to be a very efficient tool for the precise computation of critical quantities. In …

A bstract Much of our understanding of critical phenomena is based on the notion of
Renormalization Group (RG), but the actual determination of its fixed points is usually based …

It is expected that conformal symmetry is an emergent property of many systems at their
critical point. This imposes strong constraints on the critical behavior of a given system …

Active matter is not only relevant to living matter and diverse nonequilibrium systems, but
also constitutes a fertile ground for novel physics. Indeed, dynamic renormalization group …

The search for controlled approximations to study strongly coupled systems remains a very
general open problem. Wilson's renormalization group has shown to be an ideal framework …

We revisit the approach to the lower critical dimension d lc in the Ising-like φ 4 theory within
the functional renormalization group by studying the lowest approximation levels in the …

Using the nonperturbative functional renormalization group (FRG) within the Blaizot-Méndez-
Galain-Wschebor approximation, we compute the operator product expansion (OPE) …

We construct exact solutions to the functional renormalisation group equation of the O (N)
model and the Gross–Neveu model at large N for 2< d< 4, without specifying the form of the …

We revisit the question concerning the stability of nonuniform superfluid states of the Fulde-
Ferrell-Larkin-Ovchinnikov (FFLO) type to thermal and quantum fluctuations. On general …

The nonperturbative functional renormalization group equation depends on the choice of a
regulator function, whose main properties are a “coarse-graining scale” k and an overall …
