Theory of interlayer tunneling in bi-layer quantum Hall ferromagnets
Ady Stern, S. M. Girvin, A. H. MacDonald +1
Spielman et al. have recently observed a large zero-bias peak in the tunnel conductance of a bi-layer system in a quantum Hall ferromagnet state. We argue that disorder-induced top…
Strong Correlation to Weak Correlation Phase Transition in Bilayer Quantum Hall Systems
John Schliemann, S. M. Girvin, A. H. MacDonald
At small layer separations, the ground state of a nu=1 bilayer quantum Hall system exhibits spontaneous interlayer phase coherence and has a charged-excitation gap E_g. The evoluti…
Reorientation of Anisotropy in a Square Well Quantum Hall Sample
W. Pan, T. Jungwirth, H. L. Stormer +7
We have measured magnetotransport at half-filled high Landau levels in a quantum well with two occupied electric subbands. We find resistivities that are {\em isotropic} in perpend…
