Discovering and quantifying nontrivial fixed points in multi-field models
We use the functional renormalization group and the [Formula: see text] -expansion concertedly to explore multicritical universality classes for coupled [Formula: see text] vector-field models in three Euclidean dimensions. Exploiting the complementary strengths of these two methods we show how to m...
