Unconventional fractional quantum Hall states and Wigner crystallization in suspended Corbino graphene

Unconventional fractional quantum Hall states and Wigner crystallization in suspended Corbino graphene

Understanding of ordered phases of interacting electrons in 2D systems is a fundamental many-body physics problem. Here, the authors report unconventional fractional quantum Hall phases in graphene Corbino devices originating from residual interactions of composite fermions in partially filled highe...

description Understanding of ordered phases of interacting electrons in 2D systems is a fundamental many-body physics problem. Here, the authors report unconventional fractional quantum Hall phases in graphene Corbino devices originating from residual interactions of composite fermions in partially filled higher Landau levels. They also demonstrate the exceptional strength of the Coulomb interactions in suspended graphene by reaching the field-induced Wigner crystal state.
