Abstract: The effect of quenched random fields on classical and quantum critical behaviour is studied by means of the ϵ-analysis for a number of systems. The investigation is performed in terms of a generalized random-field correlation function. The interplay of short-range correlations as well as of a parameter-dependent variety of long-range correlations with thermal and quantum fluctuations is revealed.
