The phi-4 model is the canonical model to study the continuous phase transition. In reality, experimental systems have defects. How does the presence of these defects influence the phase transition ? This question was studied within the phi-4 model by adding a quenched randomness to the coupling constants in the phi-4 model and applying replica renormalization group (RG) techniques. Recently while exploring effect of anisotropy in neuronal connections we introduced a model with quenched anisotropic disorder. In this work, we introduce such a disorder to the phi-4 model and study its consequences.
