Interpolation formulas for asymptotically safe cosmology
S. Nagy, K. Sailer
Simple interpolation formulas are proposed for the description of the renormalization group (RG) scale dependences of the gravitational couplings in the framework of the 2-paramete…
Phase structure of the ghost model with higher-order gradient term
Z. Péli, S. Nagy, K. Sailer
The phase structure and the infrared behaviour of the Euclidean 3-dimensional symmetric ghost scalar field model with higher-order derivative term has been investigated in W…
Particle in a cavity in one-dimensional bandlimited quantum mechanics
K. Sailer, Z. Peli, S. Nagy
The effects of the generalized uncertainty principle (GUP) on the low-energy stationary states of a particle moving in a cavity with no sharp boundaries are determined by means of…
Infrared fixed point in quantum Einstein gravity
S. Nagy, J. Krizsan, K. Sailer
We performed the renormalization group analysis of the quantum Einstein gravity in the deep infrared regime for different types of extensions of the model. It is shown that an attr…
Interplay of fixed points in scalar models
S. Nagy, K. Sailer
We performed the renormalization group analysis of scalar models exhibiting spontaneous symmetry breaking. It is shown that an infrared fixed point appears in the broken symmetric…
Renormalization of QCD_2
J. Kovacs, S. Nagy, I. Nandori +1
The low energy infrared scaling of the multi-color 2-dimensional quantum chromodynamics is determined in the framework of its bosonized model by using the functional renormalizatio…
Quantum censorship in two dimensions
V. Pangon, S. Nagy, J. Polonyi +1
It is pointed out that increasingly attractive interactions, represented by partially concave local potential in the Lagrangian, may lead to the degeneracy of the blocked, renormal…
Onset of symmetry breaking by the functional RG method
V. Pangon, S. Nagy, J. Polonyi +1
A numerical algorithm is used to solve the bare and the effective potential for the scalar model in the local potential approximation. An approximate dynamical Maxwell-cut is…
Periodic ground state for the charged massive Schwinger model
S. Nagy, J. Polonyi, K. Sailer
It is shown that the charged massive Schwinger model supports a periodic vacuum structure for arbitrary charge density, similar to the common crystalline layout known in solid stat…
Response of an electron system to a periodic potential
S. Nagy, K. Sailer
We give a quantum field theoretical treatment of a one dimensional electron system with a fixed chemical potential . The non-perturbative Lindhard response function is found for…
