The 2nd International Workshop "Topology: the New Horizon of Materials Science and Nanophotonics" was held at the auditorium in the WPI-MANA building over two days on June 12 (Wed) and 13 (Thu), 2019.

Recent years have seen a surge of research interest on topological states in electronic systems and related quantum matters. The concept of topology has been extended to various systems and physical waves, and the realization of new characteristics, new devices and innovative functions are strongly expected. In 2014, WPI-MANA invited the top researchers in the field of topology and physics, and organized the 1st International Workshop "Topology: in the New Frontiers of Materials Science."

This workshop also served as a kick off meeting of the JST CREST project "Creation of novel topological states and innovative functionality based on artificial graphene" that started in October 2018. Inviting Professor F. Duncan M. Haldane (Nobel Laureate in Physics 2016) from Princeton University (USA) as the keynote lecturer, the workshop consisted of 15 invited speakers from overseas, 8 invited speakers from Japan, and 3 speakers from MANA. Active discussions and opinion exchanges took place in concern with the latest research findings on topological materials science and nanophotonics, as well as the future development of these research fields.

A total of 141 participants, including 80 external researchers, attended the workshop, which confirms the high interest in this research field.
