| Outline of Final Research Achievements |
This project aims at observing the anyonic statistics of fractional quantum Hall quasiparticles, which are elementary excitations in fractional quantum Hall systems. For this purpose we explored experimental techniques for realizing a collision experiment for fractional quasiparticles. Toward this goal, [1] we studied propagation eigenmodes along quantum Hall edge channels and observed spin-charge separation in co-propagating edge channels and [2] we investigated charge and spin states at a beam splitter formed in a quantum Hall system. In addition, [3] we found that a junction between fractional and integer quantum Hall systems works as a platform for realizing a quasiparticles' collision experiment. We observed spontaneous edge reconstruction and Andreev reflection of fractional quasiparticles at the junction.
