Signatures of triplet superconductivity in ν = 2 chiral Andreev states

Abstract

We study the behavior of the conductance and the current noise in three-terminal configurations of edge modes of a quantum Hall system in the 𝜈=2 filling factor with normal and 𝑠-wave superconducting contacts. We discuss the impact of spin-orbit coupling in the quantum Hall system and the possibility of effectively inducing triplet pairing in the edge states. We show that the presence of these correlations imprints very clear signatures in both the nonlinear conductance and noise in these type of devices.
