Topologically nontrivial phases host new phenomena in matter such as topological surface states, topological superconductors, Weyl semi-metals, AQHE etc. In many cases, they are classified as topologically nontrivial materials by kinds of symmetries and these topological properties are fundamental features in basic science. For instance, the interface between normal and abnormal phases presents topologically protected states due to the change of axionic field related to symmetries. In addition, a variety of exotic phenomena converge on the theory of topology. This workshop will focus on new exotic phenomena in various materials due to the topologically nontrivial phases, which is a milestone in new research and development. We expect an interactive workshop with lively discussions between pioneers who are actively working on this field.
