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…

-Nontrivial Moiré Minibands and Interaction-Driven Quantum Anomalous Hall Insulators in Topological Insulator Based Moiré Heterostructures
Kaijie Yang, Zian Xu, Yanjie Feng +6
We studied electronic band structure and topological property of a topological insulator thin film under a moiré superlattice potential to search for two-dimensional (2D) $\mathbb…
