Hybridization of topologically distinct quartet modes in three-terminal graphene Josephson junctions
Asmaul Smitha Rashid, Le Yi, Takashi Taniguchi +4
Multiterminal Josephson junctions offer a powerful playground for exploring exotic superconducting and topological phenomena beyond the reach of conventional two-terminal devices.…
Building 3D superconductor-based Josephson junctions using a via transfer approach
Cequn Li, Le Yi, Kalana D. Halanayake +8
The coupling of superconductivity to unconventional materials may lead to novel quantum states and potential applications. Controlling the quality of the superconductor-normal meta…
Non-Hermitian Dynamics in Quantum Anomalous Hall Insulators
Le Yi, Emma Steinebronn, Asmaul Smitha Rashid +4
Magnetically doped topological insulators (TIs) exhibit two distinct phases: the quantum anomalous Hall (QAH) phase when the Fermi level resides within the surface gap, and a metal…
Nonequilibrium Andreev resonances in ballistic graphene Andreev interferometers
Asmaul Smitha Rashid, Le Yi, Takashi Taniguchi +4
We study nonequilibrium Andreev resonances in a voltage-biased graphene three-terminal Josephson junction (JJ). We observe periodic oscillations of resistance with maxima at multip…
