Effect of droplet configurations within the functional renormalization group of the Ising model approaching the lower critical dimension
Ivan Balog, Lucija Nora Farkaš, Maroje Marohnić +1
We explore the application of the nonperturbative functional renormalization group (NPFRG) within its most common approximation scheme based on truncations of the derivative expans…
Approach to the lower critical dimension of the theory in the derivative expansion of the Functional Renormalization Group
Lucija Nora Farkaš, Gilles Tarjus, Ivan Balog
We revisit the approach to the lower critical dimension in the Ising-like theory within the functional renormalization group by studying the lowest approximation…
Critical probability distributions of the order parameter from the functional renormalization group
I. Balog, A. Rançon, B. Delamotte
We show that the functional renormalization group (FRG) allows for the calculation of the probability distribution function of the sum of strongly correlated random variables. On t…
Conformal invariance in the nonperturbative renormalization group: a rationale for choosing the regulator
Ivan Balog, Gonzalo De Polsi, Matthieu Tissier +1
Field-theoretical calculations performed in an approximation scheme often present a spurious dependence of physical quantities on some unphysical parameters associated with the det…
Precision calculation of critical exponents in the universality classes with the nonperturbative renormalization group
Gonzalo De Polsi, Ivan Balog, Matthieu Tissier +1
We compute the critical exponents , and of models for various values of by implementing the derivative expansion of the nonperturbative renormalization group…
Convergence of Non-Perturbative Approximations to the Renormalization Group
Ivan Balog, Hugues Chaté, Bertrand Delamotte +2
We provide analytical arguments showing that the non-perturbative approximation scheme to Wilson's renormalisation group known as the derivative expansion has a finite radius of co…
