Joel E. Moore
Joel Moore received his A.B. from Princeton and Ph.D. from MIT for theoretical work on the fractional quantum Hall effect. He was a graduate fellow at the Kavli Institute for Theoretical Physics and postdoctoral researcher at Bell Labs before moving to the University of California, Berkeley, and Lawrence Berkeley Laboratory in 2002. His current research interests are in the collective quantum physics of electrons and atoms, including the recently discovered “topological insulators,” and in applications of quantum information concepts to condensed matter physics.
Quasiparticles do the twist
A theoretical analysis of recent experiments suggests that a key feature of a topological quantum computer—the unusual statistics of quasiparticles in the quantum Hall effect—may finally have been observed. Read More »
