A Chiral Superlattice Route to Spin-Split Topological Antiferromagnetism
Thao Dinh, Mengke Liu, Jian-Xiang Qiu +48
The interplay between chirality and magnetism is a profound topic, spanning particle physics, condensed matter, chemistry and origin of life. In this paper, we study this interplay…
Observation of the Axion quasiparticle in 2D MnBiTe
Jian-Xiang Qiu, Barun Ghosh, Jan Schütte-Engel +32
In 1978, Wilczek and Weinberg theoretically discovered a new boson-the Axion-which is the coherent oscillation of the field in QCD. Its existence can solve multiple fundamental…
An antiferromagnetic diode effect in even-layered MnBi2Te4
Anyuan Gao, Shao-Wen Chen, Barun Ghosh +26
In a PN junction, the separation between positive and negative charges leads to diode transport. In the past few years, the intrinsic diode transport in noncentrosymmetric polar co…
Quantum metric nonlinear Hall effect in a topological antiferromagnetic heterostructure
Anyuan Gao, Yu-Fei Liu, Jian-Xiang Qiu +28
Quantum geometry - the geometry of electron Bloch wavefunctions - is central to modern condensed matter physics. Due to the quantum nature, quantum geometry has two parts, the real…
Nonlinear optical diode effect in a magnetic Weyl semimetal
Christian Tzschaschel, Jian-Xiang Qiu, Xue-Jian Gao +18
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Opt…
Axion optical induction of antiferromagnetic order
Jian-Xiang Qiu, Christian Tzschaschel, Junyeong Ahn +25
Using circularly-polarized light to control quantum matter is a highly intriguing topic in physics, chemistry and biology. Previous studies have demonstrated helicity-dependent opt…
Higher-order topological states in photonic Thue-Morse quasicrystals: quadrupole insulator and a new origin of corner states
Langlang Xiong, Yu Zhang, Yufu Liu +2
Corner states (CSs) in higher-order topological insulators (HOTIs) have recently been of great interest in both crystals and quasicrystals. In contrast to electronic systems, HOTIs…
Topological properties of two-dimensional photonic square lattice without and symmetries
Langlang Xiong, Yufu Liu, Yu Zhang +2
Rich topological phenomena, edge states and two types of corner states, are unveiled in a two-dimensional square-lattice dielectric photonic crystal without both and $M_{x(y)…
Layer Hall effect in a 2D topological Axion antiferromagnet
Anyuan Gao, Yu-Fei Liu, Chaowei Hu +33
While ferromagnets have been known and exploited for millennia, antiferromagnets (AFMs) were only discovered in the 1930s. The elusive nature indicates AFMs' unique properties: At…
Bond-breaking Induced Lifshitz Transition in Robust Dirac Semimetal
Yiyuan Liu, Yu-Fei Liu, Xin Gui +7
Topological electrons in semimetals are usually vulnerable to chemical doping and environment change, which restricts their potential application in future electronic devices. In t…
