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…
Corner Multifractality for Reflex Angles and Conformal Invariance at 2D Anderson Metal-Insulator Transition with Spin-Orbit Scattering
Hideaki Obuse, Arvind R. Subramaniam, Akira Furusaki +2
We investigate boundary multifractality of critical wave functions at the Anderson metal-insulator transition in two-dimensional disordered non-interacting electron systems with sp…
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…
