Interlayer-correlated fractional quantum Hall state in a trilayer electron system
Chengyu Wang, C. T. Tai, N. Toemtrisna +4
In multilayer quantum Hall systems, when the layer separation is sufficiently small, the interplay between intralayer and interlayer Coulomb interactions can lead to exotic, multi-…
