Rashba spin-orbit coupling and artificially engineered topological superconductors
Sankar Das Sarma, Katharina Laubscher, Haining Pan +2
One of the most important physical effects in condensed matter physics is the Rashba spin-orbit coupling (RSOC), introduced in seminal works by Emmanuel Rashba. In this article, we…
Fractional chiral second-order topological insulator from a three-dimensional array of coupled wires
Viktoriia Pinchenkova, Katharina Laubscher, Jelena Klinovaja
We construct a model of a three-dimensional chiral second-order topological insulator (SOTI) from an array of weakly coupled nanowires. We show that, in a suitable parameter regime…
Singlet-only Always-on Gapless Exchange Qubits with Baseband Control
Nathan L. Foulk, Silas Hoffman, Katharina Laubscher +1
We propose a singlet-only always-on gapless exchange (SAGE) spin qubit that encodes a single qubit in the spins of four electrons while allowing universal baseband control. While c…
