TITLE: "Convincing electrons to live in a 2D world, and other sleights of hand"

SPEAKER: Dr. Mark Eriksson,

PLACE: George P. Williams, Jr. Lecture Hall, (Olin 101)

One of the miracles of modern technology is the ability to squeeze electrons into layers so thin that they behave as if the world were two-dimensional. The interesting behavior of electrons living in a flat world is responsible for the quantum Hall effects, this year the subject of a second Nobel prize. I will present an introduction to these systems, and describe some of our work which shows how lowering the density of electrons in the two-dimensional layer dramatically changes the physics of electrons in flatland.
