Numerical Accuracy of the Derivative-Expansion-Based Functional Renormalization Group

Andrzej Chlebicki

We investigate the precision of the numerical implementation of the functional renormalization group based on extracting the eigenvalues from the linearized RG transformation. For…

Low-temperature behavior of the $O (N)$ models below two dimensions

Andrzej Chlebicki, Paweł Jakubczyk

We investigate the critical behavior and the nature of the low-temperature phase of the $O (N)$ models treating the number of field components $N$ and the dimension $d$ as continuou…

$Z_{4}$ -symmetric perturbations to the XY model from functional renormalization

Andrzej Chlebicki, Carlos A. Sánchez-Villalobos, Pawel Jakubczyk +1

We employ the second order of the derivative expansion of the nonperturbative renormalization group to study cubic ( $Z_{4}$ -symmetric) perturbations to the classical $X Y$ mo…

Analyticity of critical exponents of the $O (N)$ models from nonperturbative renormalization

Andrzej Chlebicki, Pawel Jakubczyk

We employ the functional renormalization group framework at the second order in the derivative expansion to study the $O (N)$ models continuously varying the number of field compone…

Criticality of the $O (2)$ model with cubic anisotropies from nonperturbative renormalization

Andrzej Chlebicki, Pawel Jakubczyk

We study the $O (2)$ model with $Z_{4}$ -symmetric perturbations within the framework of nonperturbative renormalization group (RG) for spatial dimensionality $d = 2$ and $d = 3$ .…
