A Complete Renormalization Group Trajectory between Two Fixed Points
We give a rigorous nonperturbative construction of a massless discrete trajectory for Wilson’s exact renormalization group. The model is a three dimensional Euclidean field theory with a modified free propagator. The trajectory realizes the mean field to critical crossover from the ultraviolet Gaussian fixed point to an analog recently constructed by Brydges, Mitter and Scoppola of the Wilson-F...
متن کاملNonthermal fixed points and the functional renormalization group
Nonthermal fixed points represent basic properties of quantum field theories, in addition to vacuum or thermal equilibrium fixed points. The functional renormalization group on a closed real-time path provides a common framework for their description. For the example of an O(N) symmetric scalar theory it reveals a hierarchy of fixed point solutions, with increasing complexity from vacuum and th...

In this note we construct hyperbolic fixed points for cylinder renormalization of maps with Siegel disks.
متن کاملComplex networks renormalization: flows and fixed points.
Recently, it has been claimed that some complex networks are self-similar under a convenient renormalization procedure. We present a general method to study renormalization flows in graphs. We find that the behavior of some variables under renormalization, such as the maximum number of connections of a node, obeys simple scaling laws, characterized by critical exponents. This is true for any cl...

The models tha t we consider are 1-dimensionM ferromagnets with a ra ther peculiar, nontranslat ionMly invar iant interact ion [1-4]. I t will be seen tha t the special form of this interact ion leads to a ra ther simple formulat ion of the renormalizat ion group equation. Apar t f rom the lack of t ranslat ion invariance these models are supposed to behave in m a n y respects like ordinary 1-d...
