Titre Current correlations out of equilibrium in an electron collider
Résumé Recent experiments with quantum Hall edge states allowed one to measure current correlations in an electron collider, where a pair of non-equilibrium edge states are scattered across a quantum point contact. In the fractional quantum Hall regime this setting offered a possibility to test anyon statistics of quasiparticles. Remarkably, in the integer quantum Hall regime at \nu=2 when the system is driven out of equilibrium by a finite bias voltage, the measurements showed unexpected results. In this talk I will discuss a theoretical model of these experiments, and will present an exact solution of this model which explains the experimental observations.
