Axion Insulator State in Hundred-Nanometer-Thick Magnetic Topological Insulator Sandwich Heterostructures
Deyi Zhuo, Zi-Jie Yan, Zi-Ting Sun +10
An axion insulator is a three-dimensional (3D) topological insulator (TI), in which the bulk maintains the time-reversal symmetry or inversion symmetry but the surface states are g…
Layer-by-layer disentanglement of Bloch states via frequency-domain photoemission
Woojoo Lee, Sebastian Fernandez-Mulligan, Hengxin Tan +8
Layer-by-layer material engineering has enabled exotic quantum phenomena such as interfacial superconductivity and the quantum anomalous Hall effect. Meanwhile, deciphering electro…
Strong Room-Temperature Bulk Nonlinear Hall Effect in a Spin-Valley Locked Dirac Material
Lujin Min, Hengxin Tan, Zhijian Xie +8
Nonlinear Hall effect (NLHE) is a new type of Hall effect with wide application prospects. Practical device applications require strong NLHE at room temperature (RT). However, prev…
Hierarchy of quasi-symmetries and degeneracies in chiral crystal materials CoSi
Lun-Hui Hu, Chunyu Guo, Yan Sun +5
In materials, certain approximated symmetry operations can exist in a lower-order approximation of the effective model but are good enough to influence the physical responses of th…
Confinement-Induced Chiral Edge Channel Interaction in Quantum Anomalous Hall Insulators
Ling-Jie Zhou, Ruobing Mei, Yi-Fan Zhao +8
In quantum anomalous Hall (QAH) insulators, the interior is insulating but electrons can travel with zero resistance along one-dimensional conducting paths known as chiral edge cha…
Nonsymmorphic Symmetry Protected Dirac, Möbius, and Hourglass Fermions in Topological Materials
Rui-Xing Zhang, Chao-Xing Liu
A lattice symmetry, if being nonsymmorphic, is defined by combining a point group symmetry with a fractional lattice translation that cannot be removed by changing the lattice orig…
