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…
Functional renormalization group approach to the sine-Gordon model
S. Nagy, I. Nandori, J. Polonyi +1
The renormalization group flow is presented for the two-dimensional sine-Gordon model within the framework of the functional renormalization group method by including the wave-func…
Renormalization group in the internal space
J. Polonyi, K. Sailer
Renormalization group in the internal space consists of the gradual change of the coupling constants. Functional evolution equations corresponding to the change of the mass or the…
Renormalization of composite operators
J. Polonyi, K. Sailer
The blocked composite operators are defined in the one-component Euclidean scalar field theory, and shown to generate a linear transformation of the operators, the operator mixing.…
Fate of the classical false vacuum
Sz. Borsanyi, A. Patkos, J. Polonyi +1
Thermalisation of configurations with initial white noise power spectrum is studied in numerical simulations of a classical one-component theory in 2+1 dimensions, coupled to…
Renormalization group for the internal space
Jean Alexandre, Janos Polonyi
The renormalization group method is a successive integration over the fluctuations which are ordered according to their length scale, a parameter in the external space. A different…
