Abstract

The bicritical and tetracritical phenomena and scaling properties of simultaneous ordering (SO) theory were studied. The stability of decoupled fixed point (DFP) was analyzed to characterize the multicritical point. Analysis suggested that the renormalization group (RG) flow away from the vicinity of unstable isotropic fixed point (IFP) for continuous transition. Measurements of isotropic 5-component critical exponents showed that the multicritical point characterized the simultaneous ordering of SO(3) component and superconducting component order parameters.
