Quantum Coherence of Edge States in the Quantum Hall Eect { Topological Invariants and Edge State Mixing {
Edge states in the integral quantum Hall e ect on a lattice are reviewed from a topological point of view. For a system with edges which is realized inevitably in an experimental situation, the Hall conductance xy is given by a winding number of the edge state on a complex energy surface. A relation between two topological invariants (bulk and edge) is also clari ed. In a macroscopic system, mi...
متن کاملDynamical properties of quantum Hall edge states.
We consider the dynamical properties of simple edge states in integer (ν = 1) and fractional (ν = 1/2m + 1) quantum Hall (QH) liquids. The influence of a time-dependent local perturbation on the ground state is investigated. It is shown that the orthogonality catastrophe occurs for the initial and final state overlap | < i|f > | ∼ L − 1 2ν (δ π) 2 with the phase shift δ. The transition probabil...
متن کاملBinding Transition in Quantum Hall Edge States
We study a class of Abelian quantum Hall (QH) states which are topologically unstable (T-unstable). We find that the T-unstable QH states can have a phase transition on the edge which causes a binding between electrons and reduces the number of gapless edge branches. After the binding transition, the single-electron tunneling into the edge gains a finite energy gap, and only certain multi-elect...
متن کاملEdge reconstruction in fractional quantum Hall states
The nature of edge reconstruction in the quantumHall e ect (QHE) and the issue of where the current flows have been debated for years.Moreover, the recent observation of proliferation of ‘upstream’ neutral modes in the fractional QHE has raised doubts about the present models of edge channels. Here, we present a new picture of the edge reconstruction in two of the holeconjugate states. For exam...
متن کاملShot-noise thermometry of the quantum Hall edge States.
We use the nonequilibrium bosonization technique to investigate the effects of the Coulomb interaction on quantum Hall edge states at a filling factor ν=2, partitioned by a quantum point contact (QPC). We find that, due to the integrability of charge dynamics, edge states evolve to a nonequilibrium stationary state with a number of specific features. In particular, the noise temperature Θ of a ...
