Relationship between the Electronic Polarization and the Winding Number in Non-Hermitian Systems
Shohei Masuda, Masaaki Nakamura
We discuss an extension of the Resta's electronic polarization to non-Hermitian systems with periodic boundary conditions. We introduce the ``electronic polarization'' as an expect…

Characterization of topological insulators based on the electronic polarization with spiral boundary conditions
Masaaki Nakamura, Shohei Masuda, Satoshi Nishimoto
We introduce the electronic polarization originally defined in one-dimensional lattice systems to characterize two-dimensional topological insulators. The main idea is to use spira…
