Exciton condensation in quantum Hall bilayers at total filling ν T = 5
We study the coupled quantum Hall bilayers each at half-filled first excited Landau levels by varying the layer distance. Based on numerical exact diagonalization on a torus, we identify two distinct phases separated by a critical layer distance dc. From dc to an infinite layer distance, the topolog...

Summary: | We study the coupled quantum Hall bilayers each at half-filled first excited Landau levels by varying the layer distance. Based on numerical exact diagonalization on a torus, we identify two distinct phases separated by a critical layer distance dc. From dc to an infinite layer distance, the topological phase is smoothly connected to a direct tensor product of two Moore-Read states, while interlayer coherence emerges at d |
