Interlayer Coherence in the $\nu =1$ and $\nu =2$ Bilayer Quantum Hall States

A. Sawada, Z. F. Ezawa, H. Ohno +6

We have measured the Hall-plateau width and the activation energy of the bilayer quantum Hall (BLQH) states at the Landau-level filling factor $\nu =1$ and 2 by tilting the sample and…
