Interlayer Coupling-Induced Quantum Phase Transition in Quantum Anomalous Hall Multilayers
Ling-Jie Zhou, Deyi Zhuo, Ruobing Mei +8
A quantum phase transition arises from competition between different ground states and is typically accessed by varying a single physical parameter near absolute zero temperature.…
