Multiband models for field theories with anomalous current dimension (1504.02478v3)
Published 9 Apr 2015 in hep-th and cond-mat.str-el
Abstract: We give simple examples of weakly coupled or free quantum mechanical systems that exhibit scale invariance with an anomalous dimension for a conserved current. In these models scaling as an exact symmetry only emerges in a large N limit, but it remains as an approximate symmetry even at finite N.
