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…
Z2 topological term, the global anomaly, and the two-dimensional symplectic symmetry class of Anderson localization
Shinsei Ryu, Christopher Mudry, Hideaki Obuse +1
We discuss, for a two-dimensional Dirac Hamiltonian with random scalar potential, the presence of a topological term in the non-linear sigma model encoding the physics of And…
Two-dimensional spin-filtered chiral network model for the Z_2 quantum spin-Hall effect
Hideaki Obuse, Akira Furusaki, Shinsei Ryu +1
The effects of static disorder on the Z_2 quantum spin-Hall effect for non-interacting electrons propagating in two-dimensional space is studied numerically. A two-dimensional time…
Prediction of the capacitance lineshape in two-channel quantum dots
C. J. Bolech, N. Shah
We propose a set-up to realize two-channel Kondo physics using quantum dots. We discuss how the charge fluctuations on a small dot can be accessed by using a system of two single e…
