Condensed Matter/Materials and Biological Physics Seminar November 2 Professor Smitha Vishveshwara (hosted by Seidel) Department of Physics, University of Illinois at Urbana-Champaign Fractional Statistics and Beam Splitters in Quantum Hall Systems One of the most fascinating aspects of the two dimensional world is the possible existence of anyons, particles which obey 'fractional' statistics different from fermionic and bosonic statistics. The quantum Hall system is predicted to host such entities. This talk will begin with an introduction to fractional particles in quantum Hall systems and anyons in magnetic fields. Correlations and signatures of these anyons will be discussed. Finally, schemes for detecting such anyons will be proposed, including those that follow the principles of beam splitters found in an entirely different context, that of quantum optics.
