Critical properties of quantum Hall systems are affected by the presence of extra edge channels-those that are present, in particular, at higher plateau transitions. We study this phenomenon for theâ€¦ (More)

We discuss, for a two-dimensional Dirac Hamiltonian with a random scalar potential, the presence of a Z2 topological term in the nonlinear sigma model encoding the physics of Anderson localization inâ€¦ (More)

We study the multifractality (MF) of critical wave functions at boundaries and corners at the metal-insulator transition (MIT) for noninteracting electrons in the two-dimensional (2D) spin-orbitâ€¦ (More)

We investigate boundary multifractality of critical wave functions at the Anderson metal-insulator transition in twodimensional disordered non-interacting electron systems with spin-orbit scattering.â€¦ (More)
