A machine learning is applied for a study of the higher order topological phases in our recent paper "Phase diagram of a disordered higher-order topological insulator: A machine learning study" by Hiromu Araki, Tomonari Mizoguchi and Yasuhiro Hatsugai, which is accepted for publication in Phys. Rev. B. Have a look at.

Our paper "Weyl points of mechanical diamond ", by Yuta Takahashi, Toshikazu Kariyado, Yasuhiro Hatsugai, has been published in Phys. Rev. B at the beginning of the year 2019. Weyl equation (massless Dirac equation) is applied for a description of the classical Newton dynamics with periodic structure, implying non-trivial edge states due to bulk-edge correspondence.
