Andreev reflection of fractional quasiparticles in the Quantum Hall Effect
Updated the: 05/28/2021 - 08:57

At the interface between a normal metal and a superconductor, an incoming electron can be transmitted in the superconductor as two electrons forming a Cooper pair, while a hole is reflected back in the normal metal. This is known as Andreev reflection. Researchers from the Nanophysics team of the CPT (CNRS-AMU), in collaboration with an experimental team at NTT Research Labs (Atsugi - Japan), have demonstrated that a similar behavior can be observed for fractional quasiparticles existing in the Quantum Hall effect in 2d electronic gas. This study is an important step towards the understanding and the manipulation of these fractional quasiparticles.
