Many-body Chern number without integration
Koji Kudo, Haruki Watanabe, Toshikaze Kariyado +1
The celebrated work of Niu, Thouless, and Wu demonstrated the quantization of Hall conductance in the presence of many-body interactions by revealing the many-body counterpart of t…
Generating electromagnetic modes with fine tunable orbital angular momentum by planar topological circuits
Yuan Li, Yong Sun, Weiwei Zhu +5
Metamaterials made of periodic arrangements of electric permittivity and magnetic permeability and arrays of resonators can provide optic properties unexperienced in conventional m…
Topological Aspect of Graphene Patchwork with Regular Arrays of Nano Holes
Toshikaze Kariyado, Yongcheng Jiang, Hongxin Yang +1
Triangular and honeycomb lattices are dual to each other -- if we puncture holes into a featureless plane in a regular triangular alignment, the remaining body looks like a honeyco…
Weyl points of mechanical diamond
Yuta Takahashi, Toshikaze Kariyado, Yasuhiro Hatsugai
A spring-mass model arranged in a diamond structure --- mechanical diamond --- is analyzed in terms of topology in detail. We find that, additional springs connecting the next-near…
