A spin-statistics relation for the anyonic quasiparticles of the quantum-Hall effect

The spin-statistics relation is a pillar of our description of the world. In this seminar, I will show that it is possible to introduce a measurable spin also for the quasiparticles of the quantum Hall effect, and that this spin satisfies a spin-statistics relation. I will discuss this idea in several explicit cases (including the case of Laughlin’s quasielectron) and lay down a sketch of the proof. [1,2]

Finally, I will conclude the seminar discussing the entanglement properties of FQHE wavefunctions using a Bisognano-Wichmann Hamiltonian (see Ref. [3] for a recent experiment in the non-interacting case).
