We study the quantized charge pumping of higher-order topological insulators (HOTIs) with
edge-corner correspondences based on the combination of the rotation of in-plane magnetic …

We study equilibrium crystal shapes of a topological insulator (TI), a topological crystalline
insulator (TCI) protected by mirror symmetry, and a second-order topological insulator …

Crystal symmetries play an essential role in band structures of non-Hermitian Hamiltonians.
In this paper, we propose a non-Hermitian skin effect (NHSE) enforced by nonsymmorphic …

Previous work has shown that time-reversal symmetric Weyl semimetals with a quadrupolar
arrangement of first-order Weyl nodes exhibit a mixed crystalline-electromagnetic response …

The hybridization of different topological phases is attractive because it can facilitate the
simultaneous utilization of their respective advantages. Three-dimensional (3D) higher …

Crystal symmetries play an essential role in band structures of non-Hermitian Hamiltonian.
In this letter, we propose a non-Hermitian skin effect (NHSE) enforced by nonsymmorphic …

In recent years, there has been a surge of interest in exploring higher-order topology and
their semi-metallic counterparts, particularly in the context of Dirac and Weyl semimetals …

Topology and physics share a long and eminent history. In this dissertation, we apply the
tools of topology to study the physics of electrons and phonons in periodic media. The …
