Abstract
The existence of a metallic phase between two adjacent quantum Hall (QH) phases and between a QH phase and the insulating phase was proposed. The strong inter-Landau-band mixings among these states could occur when the bandwidth was comparable to the spacing of two adjacent Landau bands. It was shown that the mixing of localized states with opposite chirality could delocalize electronic states. The numerical evidence for a metallic phase between two neighbouring QH phases was found using the level spacing statistics analysis.
