In this talk, I will discuss how geometry degree of freedoms naturally arise on the domain walls of topological phases. In particular, I will study a simple example of domain wall theory between toric code model and double semion model. It turns out that the domain wall theory is indeed a SU(2)_1 conformal field theory at low energy . I will also discuss the general math framework for the emergence of geometry on the domain walls of topological phases.
