Phase signature of topological transition in Josephson Junctions
Matthieu C. Dartiailh, William Mayer, Joseph Yuan +4
Topological superconductivity holds promise for fault-tolerant quantum computing. While planar Josephson junctions are attractive candidates to realize this exotic state, direct ph…
Gate Controlled Anomalous Phase Shift in Al/InAs Josephson Junctions
William Mayer, Matthieu C. Dartiailh, Joseph Yuan +3
In a standard Josephson junction the current is zero when the phase difference between the superconducting leads is zero. This condition is protected by parity and time-reversal sy…
In-Plane Magnetoconductance Mapping of InSb Quantum Wells
J. T. Mlack, K. S. Wickramasinghe, T. D. Mishima +2
In-plane magnetoconductance of InSb quantum wells (QW) containing a two dimensional electron gas (2DEG) is presented. Using a vector magnet, we created a magnetoconductance map whi…
Strong Electron-Electron Interactions of a Tomonaga--Luttinger Liquid Observed in InAs Quantum Wires
Yosuke Sato, Sadashige Matsuo, Chen-Hsuan Hsu +12
We report strong electron-electron interactions in quantum wires etched from an InAs quantum well, a material known to have strong spin-orbit interactions. We find that the current…
