Topological quantum number and critical exponent from conductance fluctuations at the quantum Hall plateau transition
I. C. Fulga, F. Hassler, A. R. Akhmerov +1
The conductance of a two-dimensional electron gas at the transition from one quantum Hall plateau to the next has sample-specific fluctuations as a function of magnetic field and F…
Scattering theory of topological insulators and superconductors
I. C. Fulga, F. Hassler, A. R. Akhmerov
The topological invariant of a topological insulator (or superconductor) is given by the number of symmetry-protected edge states present at the Fermi level. Despite this fact, est…
Scattering formula for the topological quantum number of a disordered multi-mode wire
I. C. Fulga, F. Hassler, A. R. Akhmerov +1
The topological quantum number Q of a superconducting or chiral insulating wire counts the number of stable bound states at the end points. We determine Q from the matrix r of refl…
