Effective continuum model of twisted bilayer GeSe and origin of emerging one-dimensional mode
Manato Fujimoto, Toshikaze Kariyado
The electric structure of twisted bilayer GeSe, which shows a rectangular moiré pattern, is analyzed using a type effective continuum model. The effective model…
Giant orbital diamagnetism of three-dimensional Dirac electrons in SrPbO antiperovskite
S. Suetsugu, K. Kitagawa, T. Kariyado +5
In Dirac semimetals, inter-band mixing has been known theoretically to give rise to a giant orbital diamagnetism when the Fermi level is close to the Dirac point. In BiSb$…
Flat band in twisted bilayer Bravais lattices
Toshikaze Kariyado, Ashvin Vishwanath
Band engineering in twisted bilayers of the five generic two-dimensional Bravais networks is demonstrated. We first derive symmetry-based constraints on the interlayer coupling, wh…
-fluxes, semi-metals and flat bands in artificial materials
Toshikaze Kariyado, Robert-Jan Slager
The possibility of engineering experimentally viable systems that realize gauge fluxes within plaquettes of hopping have been subject of search for decades due to vast amounts of t…
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…
