Noise dephasing in the edge states of the Integer Quantum Hall regime
P. Roulleau, F. Portier, P. Roche +4
An electronic Mach Zehnder interferometer is used in the integer quantum hall regime at filling factor 2, to study the dephasing of the interferences. This is found to be induced b…

Direct measurement of the coherence length of edge states in the Integer Quantum Hall Regime
P. Roulleau, F. Portier, P. Roche +4
We have determined the finite temperature coherence length of edge states in the Integer Quantum Hall Effect (IQHE) regime. This was realized by measuring the visibility of electro…
