Predicting topological materials: symmetry-based indicator theories and beyond
Tiantian Zhang, Shuichi Murakami
Though symmetry-based indicators formulae are powerful in diagnosing topological states with a gapped band structure at/between any high-symmetry points, it fails in diagnosing top…
Kinetic magnetoelectric effect in topological insulators
Ken Osumi, Tiantian Zhang, Shuichi Murakami
The kinetic magnetoelectric effect is an orbital analogue of the Edelstein effect and offers an additional degree of freedom to control magnetisation via the charge current. Here w…
General corner charge formula in two-dimensional C_n-symmetric higher-order topological insulators
Ryo Takahashi, Tiantian Zhang, Shuichi Murakami
In this paper, we derive a general formula for the quantized fractional corner charge in two-dimensional C_n-symmetric higher-order topological insulators. We assume that the elect…
Topological phonons in oxide perovskites controlled by light
Bo Peng, Yuchen Hu, Shuichi Murakami +2
Perovskite oxides exhibit a rich variety of structural phases hosting different physical phenomena that generate multiple technological applications. We find that topological phono…
Observation of a Chiral Wave Function in Twofold Degenerate Quadruple Weyl System BaPtGe
Haoxiang Li, Tiantian Zhang, A. Said +10
Topological states in quantum materials are defined by non-trivial topological invariants, such as the Chern number, which are properties of their bulk wave functions. A remarkable…
Theory of inversion- protected topological chiral hinge states and its applications to layered antiferromagnets
Yutaro Tanaka, Ryo Takahashi, Tiantian Zhang +1
We study positions of chiral hinge states in higher-order topological insulators (HOTIs) with inversion symmetry. First, we exhaust all possible configurations of the hinge states…
