Physics Colloquium: "Spotting the elusive Majorana under the microscope"

Date: 9/27/2017
Time: 4 p.m.

Event Contact: Stephanie Johansson

Department of Physics

Event Type: Seminar/Symposium

Ettore Majorana famously considered that there may be fermions in nature that are their own antiparticle — and then he mysteriously disappeared just after proposing the idea in 1938. In recent years, we have learned how to engineer materials that harbor quasiparticles that behave as the fermions Majorana had envisioned. I will discuss how Majoranas in materials have exotic properties beyond just being their own antiparticles and their potential for creating a quantum computer.  In this talk, I will describe how we can now create materials that harbor Majorana fermions and our unique ability to visualize them. More recent experiments detecting unique spin signature of Majorana will be also discussed.
