Quadrupole Insulator without Corner States in the Energy Spectrum
Yu-Liang Tao, Jiong-Hao Wang, Yong Xu
The quadrupole insulator is a well-known instance of higher-order topological insulators in two dimensions, which possesses midgap corner states in both the energy spectrum and ent…

Higher-order Topological Insulators and Semimetals in Three Dimensions without Crystalline Counterparts
Yu-Feng Mao, Yu-Liang Tao, Jiong-Hao Wang +2
Quasicrystals allow for symmetries that are impossible in crystalline materials, such as eight-fold rotational symmetry, enabling the existence of novel higher-order topological in…

Higher-order Klein bottle topological insulator in three-dimensional acoustic crystals
Yu-Liang Tao, Mou Yan, Mian Peng +5
Topological phases of matter are classified based on symmetries, with nonsymmorphic symmetries like glide reflections and screw rotations being of particular importance in the clas…
