Coherent edge mixing and interferometry in quantum Hall bilayers
arXiv:1212.6568 · doi:10.1103/PhysRevB.87.075321
Abstract
We discuss the implementation of a beam splitter for electron waves in a quantum Hall bilayer. Our architecture exploits inter-layer tunneling to mix edge states belonging to different layers. We discuss the basic working principle of the proposed coherent edge mixer, possible interferometric implementations based on existing semiconductor-heterojunction technologies, and advantages with respect to canonical quantum Hall interferometers based on quantum point contacts.
