Non-linear Landau fan diagram for graphene electrons exposed to a moiré potential
Pilkyung Moon, Youngwook Kim, Mikito Koshino +3
Due to Landau quantization, the conductance of two-dimensional electrons exposed to a perpendicular magnetic field exhibits oscillations that generate a fan of linear trajectories…
Perpendicular electronic transport and moiré-induced resonance in twisted interfaces of three-dimensional graphite
Tenta Tani, Takuto Kawakami, Mikito Koshino
We calculate the perpendicular electrical conductivity in twisted three-dimensional graphite (rotationally stacked graphite pieces) by using the effective continuum model and the r…
Multi-scale lattice relaxation in general twisted trilayer graphenes
Naoto Nakatsuji, Takuto Kawakami, Mikito Koshino
We present comprehensive theoretical studies on the lattice relaxation and the electronic structures in general non-symemtric twisted trilayer graphenes. By using an effective cont…
Why magnetic monopole becomes dyon in topological insulators
Shoto Aoki, Hidenori Fukaya, Naoto Kan +2
The Witten effect predicts that a magnetic monopole acquires a fractional electric charge inside topological insulators. In this work, we give a microscopic description of this phe…
Topological Domain Walls in Graphene Nanoribbons with Carrier Doping
Takuto Kawakami, Gen Tamaki, Mikito Koshino
We theoretically study magnetic ground states of doped zigzag graphene nanoribbons and the emergence of topological domain walls. Using the Hartree-Fock mean-field approach and an…
Mechanical properties of 2D metal-organic and covalent-organic frameworks with non trivial topological band dispersion
Priyadarshini Kapri, Takuto Kawakami, Mikito Koshino
Using density functional theory (DFT), we investigate mechanical properties of a few 2D metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) having Dirac and flat…
