Machine Learning Study on the Flat-Band States Constructed by Molecular-Orbital Representation with Randomness
Takumi Kuroda, Tomonari Mizoguchi, Hiromu Araki +1
We study the characteristic probability density distribution of random flat band models by machine learning. The models considered here are constructed on the basis of the molecula…
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…
Entanglement Chern Number of the Kane-Mele Model with Ferromagnetism
Hiromu Araki, Toshikaze Kariyado, Takahiro Fukui +1
The entanglement Chern number, the Chern number for the entanglement Hamiltonian, is used to charac- terize the Kane-Mele model, which is a typical model of the quantum spin Hall p…
