Theoretical Evidence for the Berry-Phase Mechanism of Anomalous Hall Transport: First-principles Studies on CuCrSeBr
Yugui Yao, Yongcheng Liang, Di Xiao +4
To justify the origin of anomalous Hall effect (AHE), it is highly desirable to have the system parameters tuned continuously. By quantitative calculations, we show that the doping…
Linear magnetization dependence of the intrinsic anomalous Hall effect
Changgan Zeng, Yugui Yao, Qian Niu +1
The anomalous Hall effect is investigated experimentally and theoretically for ferromagnetic thin films of MnGe. We have separated the intrinsic and extrinsic contributions…
Geometrical phase effects on the Wigner distribution of Bloch electrons
Dimitrie Culcer, Qian Niu
We investigate the dynamics of Bloch electrons using a density operator method and connect this approach with previous theories based on wave packets. We study non-interacting syst…
Reply to Comment on "Berry phase correction to electron density of states in solids"
Di Xiao, Junren Shi, Qian Niu
The Comment by Duval et al. [PRL 96, 099701 (2006)] addresses an important, but not the main, result of our Letter [PRL 95, 137204 (2005)]. It does not contradict our results in su…
Berry phase effect in anomalous thermoelectric transport
Di Xiao, Yugui Yao, Zhong Fang +1
We develop a theory of Berry phase effect in anomalous transport in ferromagnets driven by statistical forces such as the gradient of temperature or chemical potential. Here a char…
