Boundary criticality at the Anderson transition between a metal and a quantum spin Hall insulator in two dimensions
Hideaki Obuse, Akira Furusaki, Shinsei Ryu +1
Static disorder in a noninteracting gas of electrons confined to two dimensions can drive a continuous quantum (Anderson) transition between a metallic and an insulating state when…

Quantum Hall Effect of Massless Dirac Fermions in a Vanishing Magnetic Field
Kentaro Nomura, Shinsei Ryu, Mikito Koshino +2
The effect of strong long-range disorder on the quantization of the Hall conductivity in graphene is studied numerically. It is shown that increasing Landau-level mixing p…

Electron fractionalization for two-dimensional Dirac fermions
Claudio Chamon, Chang-Yu Hou, Roman Jackiw +3
Fermion-number fractionalization without breaking of time-reversal symmetry was recently demonstrated for a field theory in -dimensional space and time that describes the co…
