Current correlations out of equilibrium in an electron collider.
Dima KOVRIZHIN
(LPTM CY Cergy Paris Université)
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.
