Super-resonant transport of topological surface states subjected to in-plane magnetic fields
Song-Bo Zhang, Chang-An Li, Francisco Peña-Benitez +4
Magnetic oscillations of Dirac surface states of topological insulators are expected to be associated with the formation of Landau levels or the Aharonov-Bohm effect. We instead st…
Higher-order Fabry-Pérot Interferometer from Topological Hinge States
Chang-An Li, Song-Bo Zhang, Jian Li +1
We propose an intrinsic 3D Fabry-Pérot type interferometer, coined "higher-order interferometer", that utilizes the chiral hinge states of second-order topological insulators and c…
Chiral Majorana Hinge Modes in Superconducting Dirac Materials
Bo Fu, Zi-Ang Hu, Chang-An Li +2
Chiral Majorana hinge modes are characteristic of a second-order topological superconductor in three dimensions. Here we systematically study pairing symmetry in the point group D_…
Topological Phase Transitions in Disordered Electric Quadrupole Insulators
Chang-An Li, Bo Fu, Zi-Ang Hu +2
We investigate disorder-driven topological phase transitions in quantized electric quadrupole insulators. We show that chiral symmetry can protect the quantization of the quadrupol…
Topological States in Generalized Electric Quadrupole Insulators
Chang-An Li, Shu-Shan Wu
The modern theory of electric polarization has recently been extended to higher multipole moments, such as quadrupole and octupole moments. The higher electric multipole insulators…
Pseudo chiral anomaly in zigzag graphene ribbons
Chang-An Li
As the three-dimensional analogs of graphene, Weyl semimetals display signatures of chiral anomaly which arises from charge pumping between the lowest chiral Landau levels of the W…
