摘要：

The generic symmetry of a system under a uniform Zeeman magnetic field is U(1) X U(1). However, we show that SO(5) models in the presence of a finite chemical potential and a finite Zeeman magnetic field can have an exact SU(2) X U(1) symmetry. This principle can be used to test SO(5) symmetry at any doping level.
