Derivative expansion for computing critical exponents of O(N) symmetric models at NNLO

Zoltán Péli

We apply the derivative expansion of the effective action in the exact renormalization group equation up to fourth order to the $Z_{2}$ and $O (N)$ symmetric scalar models in $d = 3$ Eu…

Regulator dependence of fixed points in quantum Einstein gravity with $R^{2}$ truncation

S. Nagy, B. Fazekas, Z. Peli +2

We performed a functional renormalization group analysis for the quantum Einstein gravity including a quadratic term in the curvature. The ultraviolet non-gaussian fixed point and…

Effect of the quartic gradient terms on the critical exponents of the Wilson-Fisher fixed point in $O (N)$ models

Z. Peli, S. Nagy, K. Sailer

The effect of the $\ord{\partial^4}$ terms of the gradient expansion on anomalous dimension $η$ and the correlation length's critical exponent $ν$ of the Wilson-Fisher fixed point…
