ÌáÒª (Abstract)£º

I will describe the symmetry breaking near the quantum critical point, where particle nature are gone due to the strong interaction. The holographic superconductor will be used to demonstrate the typical mechanism of such symmetry breaking. Due to the universality associated with the scale invariance of the underlying QCP, only broken symmetry types are important. According to which symmetry is broken, the fermion Green functions have characteristic features and singularity type. We classify them and get some analytic expressions in the probe limit.
