Majorana State Properties in Semiconductor and Oxide Superconducting Quantum Wires
Speaker(s): Allan MacDonald
Abstract: When proximity coupled to s-wave superconductors, quantum wires can support effective p-wave superconductivity under appropriate circumstances.  The p-wave state has  Majorana states at the wire ends which can store quantum information.  I will discuss some properties of Majorana states formed in oxide and semiconductor quantum wires, including superconducting state phase diagrams as a function of spin-orbit coupling strength, Fermi energy, and external magnetic field strength, and Majorana exchange properties.
