The Quantum Hall Effect and Spintronics
Speaker(s): Allan MacDonald
Abstract: A series of fundamental discoveries over the past thirty years has dramatically improved our ability to read, write, and process magnetically stored information. I will briefly review some of these advances before focusing on the recently discovered and particularly promising spin-orbit torques whi... read more

Exciton Condensates are Super!
Speaker(s): Allan MacDonald
Abstract: The spatially-indirect exciton condensates (SIXC) is an interesting ordered electronic state in which coherence is spontaneously established between particles localized in separate two-dimensional layers. I will discuss some of the properties SIXCs, commenting on their counterflow superfluidity, the... read more

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 propertie... read more
