Machine learning of mirror skin effects in the presence of disorder
Hiromu Araki, Tsuneya Yoshida, Yasuhiro Hatsugai
Non-Hermitian systems with mirror symmetry may exhibit mirror skin effect which is the extreme sensitivity of the spectrum and eigenstates on the boundary condition due to the non-…
Higher-order topological phases in a spring-mass model on a breathing kagome lattice
Hiromasa Wakao, Tsuneya Yoshida, Hiromu Araki +2
We propose a realization of higher-order topological phases in a spring-mass model with a breathing kagome structure. To demonstrate the existence of the higher-order topological p…
Higher-Order Topological Phase in a Honeycomb-Lattice Model with Anti-Kekulé Distortion
Tomonari Mizoguchi, Hiromu Araki, Yasuhiro Hatsugai
Higher-order topological insulators have attracted considerable interests as a novel topological phase of matter, where topologically non-trivial nature of bulk protects boundary s…
Berry Phase for Higher-Order Symmetry-Protected Topological Phases
Hiromu Araki, Tomonari Mizoguchi, Yasuhiro Hatsugai
We propose the Berry phase as a topological invariant for higher-order symmetry-protected topological (HOSPT) phases for two- and three-dimensional systems. It is to…
Phase diagram of disordered higher-order topological insulator: A machine learning study
Hiromu Araki, Tomonari Mizoguchi, Yasuhiro Hatsugai
A higher-order topological insulator is a new concept of topological states of matter, which is characterized by the emergent boundary states whose dimensionality is lower by more…
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…
