Understanding of dark universe is the main theme for particle physics and cosmology, and study of dark matter detection is one of the most important subjects for experimental studies. Now, the situation of this study is in low energy physics rather than high energy physics. Namely, new discussion for detection device or methodology might be required because energy scale is moving to lower from that of traditional high energy physics. Then, collaboration with scientists in another field will be important to come up the new method and thinking. For example, condensed matter science is one of interesting discipline for particle physics and cosmology because there are many analogies for phenomena in matter (e.g., spontaneous symmetry breaking, domain wall, monopole etc.). Optimistically new collaboration with material scientists may be able to create new something each other, and it should be important to both understand each other that expertise for young scientists.

The "axion" has also analogy between particle physics and material science, and it is very important theme for both field. In this time, I will report about the study for axion detection in the topological insulator by first collaboration with material scientists.
