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…

Induced superconducting pairing in integer quantum Hall edge states
Indium Arsenide (InAs) near surface quantum wells (QWs) are promising for the fabrication of semiconductor-superconductor heterostructures given that they allow for a strong hybridization between the
Interference of chiral Andreev edge states
The search for topological excitations such as Majorana fermions has spurred interest in the boundaries between distinct quantum states. Here, we explore an interface between two prototypical phases
Inducing superconducting correlation in quantum Hall edge states
The quantum Hall (QH) effect supports a set of chiral edge states at the boundary of a two-dimensional system. A superconductor (SC) contacting these states can provide correlations of the
Supercurrent in the quantum Hall regime
TLDR
The observation of a supercurrent in the QH regime marks an important step in the quest for exotic topological excitations, such as Majorana fermions and parafermions, which may find applications in fault-tolerant quantum computing.

TLDR
Transport through a tunnel junction connecting a superconductor to a spin-aligned quantum Hall fluid at filling \ensuremath{\nu} is studied theoretically and a nonvanishing conductance is predicted.
Current correlations of Cooper-pair tunneling into a quantum Hall system
We study Cooper-pair transport through a quantum point contact between a superconductor and a quantum Hall edge state at integer and fractional filling factors. We calculate the tunneling current and

We consider a hybrid quantum Hall-superconductor system, where a superconducting finger with oblique profile is wedged into a two-dimensional electron gas in the presence of a perpendicular magnetic
