Abstract
Using a periodic train of Lorentzian voltage pulses, which generates solitonlike electronic excitations called levitons, we investigate the charge density backscattered off a quantum point contact in the fractional quantum Hall regime. We find a regular pattern of peaks and valleys, reminiscent of analogous self-organization recently observed for optical solitons in nonlinear environments. This crystallization phenomenon is confirmed by additional side dips in the Hong-Ou-Mandel noise, a feature that can be observed in present-day electron quantum optics experiments.
