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…
Renormalizing open quantum field theories
S. Nagy, J. Polonyi
The functional renormalization group flow of a scalar field theory with quartic couplings and a sharp spatial momentum cutoff is presented in four-dimensional Minkowski space-time…
Renormalization in Minkowski space-time
I. Steib, S. Nagy, J. Polonyi
The multiplicative and the functional renormalization group methods are applied for the four dimensional scalar theory in Minkowski space-time. It is argued that the appropriate ch…
Renormalization of the bilocal sine-Gordon model
I. Steib, S. Nagy
The functional renormalization group treatment is presented for the two-dimensional sine-Gordon model by including a bilocal term in the potential, which contributes to the flow at…
Euclidean scalar field theory in the bi-local approximation
S. Nagy, J. Polonyi, I. Steib
The blocking step of the renormalization group method is usually carried out by restricting it to fluctuations and to local blocked action. The tree-level, bi-local saddle point co…
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…
