An alternative to exact renormalization equations
Jean Alexandre
An alternative point of view to exact renormalization equations is discussed, where quantum fluctuations of a theory are controlled by the bare mass of a particle. The procedure is…
A note on Liouville theory
Jean Alexandre
An exact differential equation is derived for the evolution of the Liouville effective action with the mass parameter. This derivation is based on properties of the exponential pot…
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…
Renormalization Group with Condensate
Jean Alexandre, Vincenzo Branchina, Janos Polonyi
The renormalization group is applied to the phi4 model in the symmetry broken phase in order to identify different scaling regimes. The new scaling laws reflect nonuniversal behavi…
