On the renormalization of periodic potentials
I. Nandori, J. Polonyi, K. Sailer
The renormalization of the periodic potential is investigated in the framework of the Euclidean one-component scalar field theory by means of the differential RG approach. Some kno…
The deconfinement phase transition as an Aharonov-Bohm effect
Janos Polonyi
A subjective and incomplete list of interesting and unique features of the deconfinement phase transition is presented. Furthermore a formal similarity of the density matrix of the…
Tree-level renormalization
Jean Alexandre, Janos Polonyi
It is shown in the framework of the N-component scalar model that the saddle point structure may generate non-trivial renormalization group flow. The spinodal phase separation can…
Optimization of Renormalization Group Flow
Sen-Ben Liao, Janos Polonyi, Michael Strickland
Renormalization group flow equations for scalar lambda Phi^4 are generated using three classes of smooth smearing functions. Numerical results for the critical exponent nu in three…
Periodic vacuum and particles in two dimensions
Marianne Dufour Fournier, Janos Polonyi
Different dynamical symmetry breaking patterns are explored for the two dimensional phi4 model with higher order derivative terms. The one-loop saddle point expansion predicts a ra…
Multifragmentation and the Renormalization Group
J. Polonyi
The possible usefulness of the renormalization group method in Nuclear Physics is pointed out in this talk in the context of the nuclear multifragmentation. The presentation is rat…
