Bulk versus surface: Nonuniversal partitioning of the topological magnetoelectric effect
Chao Lei, Perry T. Mahon, Allan H. MacDonald
The electronic ground state of a three-dimensional (3D) band insulator with time-reversal () symmetry or time-reversal times a discrete translation () symmetry is clas…
Symmetry, topology, and geometry: The many faces of the topological magnetoelectric effect
Perry T. Mahon, Chao Lei, Allan H. MacDonald
A delicate tension complicates the relationship between the topological magnetoelectric effect (TME) in three-dimensional (3D) topological insulators (TIs) and time-…
Pressure tunable quantum anomalous Hall states in a topological antiferromagnet
Su Kong Chong, Chao Lei, Jie Li +8
Mechanical modulation of the lattice parameter can modify the electronic structure and manipulate the magnetic coupling of a material without introducing impurities. Inspired by su…
Kerr, Faraday, and Magnetoelectric Effects in MnBiTe Thin Films
Chao Lei, Allan H. MacDonald
The topological magneto-electric effect (TME) is a characteristic property of topological insulators. In this article, we use a simplified coupled-Dirac-cone electronic structure m…
Anomalous Landau quantization in intrinsic magnetic topological insulators
Su Kong Chong, Chao Lei, Seng Huat Lee +4
The intrinsic magnetic topological insulators, Mn(Bi1-xSbx)2Te4, in their spin-aligned strong field configuration have been identified as a Weyl semimetal with single pair of Weyl…
Visualizing the interplay of Dirac mass gap and magnetism at nanoscale in intrinsic magnetic topological insulators
Mengke Liu, Chao Lei, Hyunsue Kim +5
In intrinsic magnetic topological insulators, Dirac surface state gaps are prerequisites for quantum anomalous Hall and axion insulating states. Unambiguous experimental identifica…
