A Phase Diagram for Quantum Hall Bilayers with Strong Inter-layer Correlation

Biswajit Karmakar, Vittorio Pellegrini, Aron Pinczuk +2

Inter-layer excitonic coherence in a quantum Hall bilayer with negligible tunneling is monitored by measurements of low-lying spin excitations. At ${\nu }_T=1$ new quasiparticle excita…
