Regulator dependence of fixed points in quantum Einstein gravity with 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…

Quantum-classical transition in the Caldeira-Leggett model
J. Kovacs, B. Fazekas, S. Nagy +1
The quantum-classical transition in the Caldeira-Leggett model is investigated in the framework of the functional renormalization group method. It is shown that a divergent quadrat…
