Abstract
Quantum Hall effect occurs because of the strong correlation between electrons in two dimensions in the presence of strong magnetic fields. When two parallel layers of two dimensional electron systems are coupled each other, more surprises arise. We will consider several quantum Hall states in this system, which are subtlely different from each other. These quantum Hall states can be distinguished by the novel notion of "topological order". We will propose an experiment where the distinction between different states can be made.ring the limit
that the diffusivity of Ge is much larger than that of Si.
