On the Lorentz symmetry in conformally reduced Quantum Gravity
F. Gégény, S. Nagy, K. Sailer
The functional renormalization group treatment of the conform reduced Einstein-Hilbert gravity is extended by following the evolution of the time and space derivatives separately,…
Modified renormalization group method applied to the ghost model with periodic condensate
Z. Péli, S. Nagy, K. Sailer
In order to discuss the occurrence of a periodic condensate in the Euclidean 3-dimensional ghost model, a modified version of the effective average action (EAA) renormalizat…
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…
Effect of the quartic gradient terms on the critical exponents of the Wilson-Fisher fixed point in models
Z. Peli, S. Nagy, K. Sailer
The effect of the $\ord{\partial^4}$ terms of the gradient expansion on anomalous dimension and the correlation length's critical exponent of the Wilson-Fisher fixed point…
Triple point in the ghost model with higher-order gradient term
Zoltán Péli, Sándor Nagy, Kornél Sailer
The phase structure and the infrared behaviour of the Euclidean 3-dimensional symmetric ghost scalar field has been investigated in Wegner and Houghton's renormalization…
Functional renormalization group for quantized anharmonic oscillator
S. Nagy, K. Sailer
Functional renormalization group methods formulated in the real-time formalism are applied to the symmetric quantum anharmonic oscillator, considered as a dimensional…
