Titre |
The Spin-two Quasiparticle of the Fractional Quantum Hall Effect |
|
Résumé |
Fractional quantum Hall states are strongly interacting states of two-dimensional electrons moving in a high magnetic field. It has recently been found, theoretically and experimentally, that fractional quantum Hall fluids accommodate a quasiparticle excitations carrying spin equal to 2. I will describe the general theoretical arguments leading to this conclusion. I will also show that the existence of this spin-2 mode explains a strange feature of the numerical data on the spectrum of quantum Hall systems on a sphere. |
