-mon: transmon with strong anharmonicity
Hrishikesh Patel, Vedangi Pathak, Oguzhan Can +2
We propose a novel qubit architecture based on a planar -axis Josephson junction between a thin flake -wave superconductor (SC), such as a high- cuprate BiSrC…
Edge-Ferromagnetism from Majorana Flat-Bands: Application to Split Tunneling-Conductance Peaks in the High-Tc Cuprates
Andrew C. Potter, Patrick A. Lee
In mean-field descriptions of nodal d-wave superconductors, generic edges exhibit dispersionless Majorana fermion bands at zero-energy. These states give rise to an extensive groun…
Superconductivity and Ferromagnetism in Oxide Interface Structures: Possibility of Finite Momentum Pairing
Karen Michaeli, Andrew C. Potter, Patrick A Lee
We introduce a model to explain the observed ferromagnetism and superconductivity in LAO/STO oxide interface structures. Due to the polar catastrophe mechanism, 1/2 charge per unit…
Engineering a p+ip Superconductor: Comparison of Topological Insulator and Rashba Spin-Orbit Coupled Materials
Andrew C. Potter, Patrick A. Lee
We compare topological insulator materials and Rashba coupled surfaces as candidates for engineering p+ip superconductivity. Specifically, in each type of material we examine 1) th…
Multichannel Generalization of Kitaev's Majorana End States and a Practical Route to Realize Them in Thin Films
Andrew C. Potter, Patrick A. Lee
The ends of one-dimensional p+ip superconductors have long been predicted to possess localized Majorana fermion modes. We show that Majorana end states survive beyond the strict 1D…
