Detecting crossed Andreev reflection in a quantum Hall interferometer with a superconducting beam splitter
Maxime Jamotte, Tom Menei, Manohar Kumar +2
We study time-domain electron interferometry in a Hong-Ou-Mandel (HOM) geometry, where a thin superconductor between two quantum Hall systems acts as the beam splitter. By comparin…

Landau-Level-Resolved Mode Mixing and Shot Noise in Gate-Defined Graphene Quantum Point Contacts
Shakthidhar Vilvanathan, Jerin Saji, Kristiana Frei +2
Graphene quantum point contacts (QPCs) in the quantum Hall regime host competing transport mechanisms including chiral edge propagation, valley degeneracy, and gate-induced mode mi…
