Correlated insulating states in carbon nanotubes controlled by magnetic field
Correlated insulating states in carbon nanotubes controlled by magnetic field
Recent experiments have shown that nearly metallic nanotubes remain insulating throughout magnetic field sweeps, in which the magnetic flux through the nanotube is expected to pass through a critical point where the single-particle band gap closes in one valley. Here, the authors investigate correlated insulating states of zigzag carbon nanotubes, …
