Skyrmion is a topological spin texture in which local spins point in all directions wrapping a sphere. It is present in selected helimagnet materials in a form of triangular lattice, and can be observed in various ways. In this talk, we will discuss the dynamics of Skyrmions under spin polarized current or temperature gradient. An emergent gauge field is discovered. Novel phenomena such as topological Hall effect, Skyrmion Nernst effect, and rotation of Skyrmion crystal will be presented.
