Electron and anyon collisions in mesoscopic electronic conductors

In small electronic conductors placed at low temperature, charge transport can be guided along one-dimensional ballistic channels acting as perfect quantum wires on a typical distance of few tens of microns. Combining ballistic propagation with electronic beam-splitters realized using metallic gates, electronic interferometers can be implemented allowing to understand and analyze the propagation of electrical currents as a phase coherent process that presents many analogies with the propagation of light in optics. I will more specifically discuss the geometry of the collider where charged excitations are emitted at the two inputs of a beam-splitter. The results of the collision are then analyzed by measuring the fluctuations of the electrical current transmitted towards the splitter outputs. I will present how these experiments can provide information both on the charge and on the quantum statistics of the colliding particles. I will focus in particular on the fractional quantum Hall regime occurring when a large magnetic field is applied perpendicular to a two dimensional conductor, and which hosts new excitations carrying a fractional charge and obeying fractional statistics.
