Sami Mitra, Editor, Physical Review Letters will give a special seminar, "Physics after the lab and the desk: Your work in PRL", 10:30 am, Sep. 19 (2018) at Tsukuba International Congress Center EPOCHAL TSUKUBA 2F 202. Join us !

Yuto Ashida (Univ. of Tokyo) will give a talk on Sep. 26 (2018) entitled "Quantum many-body physics in open systems: measurement and strong correlation". Its detail is here. It starts from 13:30. Join us.

I will give a talk in two coming conferences about topological phases and mathematics.

New topological number as an entanglement polarization for the topological quadrupole phases is defined and its validity is demonstrated, T. Fukui and Y, Hatsugai, Phys. Rev. B 98, 035147, (2018) . It picks up dipolar components of quadrupole phases which are canceled out in total.

I gave a series of lectures at Kyushu Univ. on the topological phases for grad. students. The detail is here [Link] . Have a look at.
