Same-spin Andreev reflections in the quantum Hall regime: the role of loss
Chun-Chia Chen, Jordan T. McCourt, John Chiles +7
The interfaces of superconductors and topological materials hold promise for realizing exotic states and excitations. An important example is provided by the chiral Andreev edge st…

Thermoelectric effect at the quantum Hall-superconductor interface
Jordan T. McCourt, John Chiles, Chun-Chia Chen +4
The interfaces of quantum Hall insulators with superconductors have emerged as a promising platform to realise interesting physics that may be relevant for topologically protected…

Fermi Velocity Dependent Critical Current in Ballistic Bilayer Graphene Josephson Junctions
Amis Sharma, Chun-Chia Chen, Jordan McCourt +6
We perform transport measurements on proximitized, ballistic, bilayer graphene Josephson junctions (BGJJs) in the intermediate-to-long junction regime (). We measure the devic…
