Right now they're working on braiding anyons.
By the way, the reason this has something to do with gravity is that space curls up like a cone around a point particle in 2DQG, i.e. flat except at the point. So there's a "phase difference" as you move a vector around a point mass. The wierd thing is that masses get larger and larger until they behave like negative masses and then go back to zero--they wrap around at 2pi. Anyons are 2-d quasiparticles with arbitrary phase as you move around them. In 3D and up, the only differences you can get are 1 and -1, bosons and fermions. -- Mike Stay metaweta@gmail.com http://math.ucr.edu/~mike
