Physics Library, Room 223A, Physics Building
The MU Physics & Astronomy Department's O. M. Stewart Colloquium Series presents, "Majorana Fermions in Dots, Chains, and Wires," Thursday, March 1, 4:00 p.m. in the Physics building library, Room 223A. Refreshments will be served beginning at 3:45 p.m.
Silas Eli Hoffman - University of Basel, Switzerland, writes, "Majorana fermions are charge-and-spinless states that reside at the end of one-dimensional topological superconductors. Their potential use as topologically stable quantum memory has compelled many experimentalists to synthesize topological superconductors in hybrid nanostructures with strong spin orbit interactions by coupling nanowires or magnetic adatoms to superconductors. Although experiments have provided evidence for Majorana fermions, a smoking gun confirmation of their existence has been elusive. Even more challenging is the operation of a Majorana qubit which has not yet been experimentally realized. To overcome these challenges, we propose alternative nanostructures which utilize quantum dots, chains of magnetic atoms, and nanowires coupled to topological superconductors to realize, detect, and manipulate Majorana fermions."
