Anomaly Matching in Gauge Theories at Finite Matter Density
We investigate the application of 't Hooft's anomaly matching conditions to
gauge theories at finite matter density. We show that the matching conditions
constrain the low-energy quasiparticle spectrum associated with possible
realizations of global symmetries.Comment: 11 pages, 1 figure, LaTeX. Section C is corrected and added
