1) TÍTULO: Anyone seen an anyon? 2) ORADORES: Jeroen van den Brink, Institute for Theoretical Solid State Physics, IFW Dresden,Helmholtzstr, Germany. 3) RESUMEN: Particles in our three-dimensional world must be either bosons or fermions: exchanging two identical particles either leaves the quantum mechanical wavefunction invariant (bosons) or causes a sign-change (fermions). Quantum mechanics in a world with only two space dimensions (2D) is much richer. In principle particles can exist…
