  We consider the effects of quantum anomalies involving the baryon current for
high-density matter. In the effective Lagrangian, the anomaly terms describe
the interaction of three light fields: the electromagnetic photons A_mu,
neutral light Nambu-Goldstone bosons (pi, eta, eta'), and the superfluid
phonon. The anomaly induced interactions lead to a number of interesting
phenomena which may have phenomenological consequences observable in neutron
stars.
