Extremely Large Anisotropy of Effective Gilbert Damping in Half-Metallic CrO2
Liangliang Guo, Ranran Cai, Zhenhua Zhang +6
Half-metals are a class of quantum materials with 100% spin-polarization at the Fermi level and have attracted a lot of attention for future spintronic device applications. CrO2 is…
Reentrant quantum anomalous Hall effect in molecular beam epitaxy-grown MnBi2Te4 thin films
Yuanzhao Li, Yunhe Bai, Yang Feng +16
In this study, we investigate intrinsic magnetic topological insulator MnBi2Te4 thin films grown by molecular beam epitaxy. We observe a reentrant quantum anomalous Hall effect whe…
Interaction induced topological phase transition in Bernevig-Hughes-Zhang model
Lei Wang, Xi Dai, X. C. Xie
We study interaction induced topological phase transition in Bernevig-Hughes-Zhang model. Topological nature of the phase transition is revealed by directly calculating the Z2 inde…
Influence of Intrinsic Electronic Properties on Light Transmission through Subwavelength Holes on Gold and MgB2 Thin Films
Xu Fang, Chenggang Zhuang, Zhenchao Wen +7
We show how intrinsic material properties modify light transmission through subwavelength hole arrays on thin metallic films in the THz regime. We compare the temperature-dependent…
Frequency domain winding number and interaction effect on topological insulators
Lei Wang, Xi Dai, X. C. Xie
We study the effect of interactions on the time reversal invariant topological insulators in four and three spatial dimensions. Their topological indices are expressed by the inter…
Transition from Integer Quantum Hall State to Insulator
X. C. Xie, D. Z. Liu
We study disorder induced transition between quantum Hall states and insulator state in a {\it lattice} model. We find the positions of the extended states do not change as disorde…
