Laughlin anyon complexes with Bose properties*

Today fractional quantum Hall effect systems are the only experimentally realized sources of anyons – quasiparticles with neither bosonic nor fermionic statistics. In presented study, a macroscopic quasi-equilibrium ensemble of neutral excitations - spin one anyon complexes in the Laughlin state ν = 1/3 were formed. To study neutral excitations, invisible by simple transport methods, we use optical pump-probe methods. The ensemble is found to have an incredibly long lifetime, and investigation by optical techniques reveals the Bose properties of ensembles.
