Andreev reflection of quantum Hall states through a quantum point contact
Mehdi Hatefipour, Joseph J. Cuozzo, Ido Levy +4
We investigate the interplay between the quantum Hall (QH) effect and superconductivity in InAs surface quantum well (SQW)/NbTiN heterostructures using a quantum point contact (QPC…
Quasiparticle dynamics in epitaxial Al-InAs planar Josephson junctions
Bassel Heiba Elfeky, William M. Strickland, Jaewoo Lee +7
Quasiparticle (QP) effects play a significant role in the coherence and fidelity of superconducting quantum circuits. The Andreev bound states of high transparency Josephson juncti…
Evolution of -periodic Supercurrent in the Presence of In-plane Magnetic Field
Bassel Heiba Elfeky, Joseph J. Cuozzo, Neda Lotfizadeh +5
In the presence of a 4-periodic contribution to the current phase relation, for example in topological Josephson junctions, odd Shapiro steps are expected to be missing. While m…
Controlling Fermi level pinning in near-surface InAs quantum wells
William M. Strickland, Mehdi Hatefipour, Dylan Langone +2
Hybrid superconductor-semiconductor heterostructures are a promising platform for quantum devices based on mesoscopic and topological superconductivity. In these structures, a semi…
