Superconducting properties of pion condensates. II

We extend previous work concerning the effect of an external magnetic field on pion condensation by including nucleons in the sigma model. We confirm that an incipient condensate can be removed by a weak field, while we argue that flux penetration for a well-developed condensate will occur in a type...

Zusammenfassung:We extend previous work concerning the effect of an external magnetic field on pion condensation by including nucleons in the sigma model. We confirm that an incipient condensate can be removed by a weak field, while we argue that flux penetration for a well-developed condensate will occur in a type-II configuration.
