Theory of quantum decoherence in macroscopic topological insulators
Xian-Peng Zhang, Yan-Qing Feng, Wanxiang Feng +1
Quantum decoherence-the loss of quantum coherence due to interactions with an environment-plays a central role in quantum transport, and controlling this ubiquitous yet inevitable…
Theory of quantum decoherence and its application to anomalous Hall effect
Xian-Peng Zhang, Yan-Qing Feng, Haiwen Liu +2
Coherent quantum phenomena can only emerge when decoherence is minimized, and mastery over decoherence is technologically crucial for designing and operating functional quantum dev…
Symmetry-driven giant magneto-optical Kerr effects in altermagnet hematite
Jiaxin Luo, Xiaodong Zhou, Jinxuan Liang +7
Altermagnets have attracted tremendous interest for revealing intriguing physics and promising spintronics applications. In contrast to conventional antiferromagnets, altermagnets…
Giant Magneto-Optical Effects in Two-Dimensional Flat-Band Antiferromagnets
Ping Yang, Wanxiang Feng, Siyuan Liu +5
In this work, we reveal giant magneto-optical responses in two-dimensional(2D) antiferromagnets with nearly flat electronic bands, based on first-principles calculations and group-…
Anomalous Hall Effect in Type IV 2D Collinear Magnets
Ling Bai, Run-Wu Zhang, Wanxiang Feng +1
We identify a previously unrecognized class of two-dimensional (2D) collinear magnetic phase that extends beyond the established categories of ferromagnets, antiferromagnets, and a…
Designing Spin-driven Multiferroics in Altermagnets
Ranquan Cao, Ruizhi Dong, Ruixiang Fei +1
Spin-driven multiferroics exhibit strong magnetoelectric coupling, with notable polarization changes under a magnetic field, but these effects are usually limited to high-Z magneti…
