A chiral quantum Hall (QH) edge state placed in proximity to an s -wave superconductor ex-periences induced superconducting correlations. Recent experiments have observed the eﬀect of proximity-coupling in QH edge states through signatures of the mediating process of Andreev reﬂection. We present the microscopic theory behind this eﬀect by modeling the system with a many-body Hamiltonian, consisting of an s -wave superconductor, subject to spin-orbit coupling and a magnetic ﬁeld, which is…
