Topological magnetoelectric pump in three dimensions
T. Fukui, T. Fujiwara
We study the topological pump for a lattice fermion model mainly in three spatial dimensions. We first calculate the U(1) current density for the Dirac model defined in continuous…

Entanglement Chern number for three-dimensional topological insulators: Characterization by Weyl points of entanglement Hamiltonians
Hiromu Araki, Takahiro Fukui, Yasuhiro Hatsugai
We propose characterization of the three-dimensional topological insulator by using the Chern number for the entanglement Hamiltonian (entanglement Chern number). Here we take the…
