Renormalization group analysis of relaxational dynamics in systems with many-component order-parameter II

Scaling fields and scaling variables

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

A general discussion of scaling fields and scaling variables in the dynamic renormalization group is given using path probability formalism. It is shown that scaling variables are the derivatives of the action with respect to scaling fields. The general ideas are illustrated on the multicomponent relaxational model in the large-n limit, where scaling fields and scaling variables are calculated explicitly and flow lines, crossover and universality are discussed. Critical points of higher order are also included in the investigation.
