Quantum Coherence of Edge States in the Quantum Hall Effect -- Topological Invariants and Edge State Mixing --

Yasuhiro Hatsugai

Edge states in the integral quantum Hall effect on a lattice are reviewed from a topological point of view. For a system with edges which is realized inevitably in an experimental…
