| Outline of Final Research Achievements |
We have summarized the outcome of the Japanese-French collaboration on SU(N) cold fermion systems in these several years in a review article published in Annals of Physics. Also in July of 2016, the Japanese-French team organized a small project-oriented workshop on SU(N) magnetism and started many projects. In 2017, they proposed a realistic way of realizing a new type of symmetry-protected topological (SPT) phases that spontaneously break inversion symmetry in a double-well optical lattice. Together with Takumi Ohta, who is a former student, we investigated dynamical properties of order parameters and entanglement in fermionic SPT phases characterized by emergent Majorana edge modes. Concerning the coupled-wire construction (CWC) of 2,3D topological phases, Immaura and Totsuka succeeded in showing the Chern-Simons gauge theory is correctly reproduced in CWC. They also provided a recipe of constructing generic 2D Abelian topological phases using CWC.
