Tunable spin textures in polar antiferromagnetic hybrid organic inorganic perovskites by electric and magnetic fields
Feng Lou, Teng Gu, Junyi Ji +3
The hybrid organic inorganic perovskites (HOIPs) have attracted much attention for their potential applications as novel optoelectronic devices. Remarkably, the Rashba band splitti…
Berezinskii-Kosterlitz-Thouless Phase in Two-dimensional Ferroelectrics
Changsong Xu, Yousra Nahas, Sergei Prokhorenko +2
The celebrated Berezinskii-Kosterlitz-Thouless (BKT) phase transition refers to a topological transition characterized, e.g., by the dissociation of vortex-antivortex pairs in two-…
Two-dimensional Topological Semimetals Protected by Symmorphic Symmetries
Wei Luo, Junyi Ji, Jinlian Lu +2
Two-dimensional (2D) band crossing semimetals (BCSMs) could be used to build a range of novel nanoscale devices such as superlenses and transistors. We find that symmorphic symmetr…
Linear versus nonlinear electro-optic effects in materials
Zhijun Jiang, Charles Paillard, Hongjun Xiang +1
Two schemes are proposed to compute the nonlinear electro-optic (EO) tensor for the first time. In the first scheme, we compute the linear EO tensor of the structure under a finite…
Unusual Intralayer Ferromagnetism Between S = 5/2 ions in MnBiTe: Role of Empty Bi States
Jing Li, J. Y. Ni, X. Y. Li +4
The layered magnetic topological insulator MnBiTe is a promising platform to realize the quantum anomalous Hall effect because its layers possess intrinsic ferromagnetism.…
Possible Kitaev Quantum Spin Liquid State in 2D Materials with S=3/2
Changsong Xu, Junsheng Feng, Mitsuaki Kawamura +6
Quantum spin liquids (QSLs) form an extremely unusual magnetic state in which the spins are highly correlated and fluctuate coherently down to the lowest temperatures, but without…
