| The í=5/2 quantum Hall state is conjectured to be a Moore-Read state. According to that, quasiparticles carry a charge of e/4 and obey non-abelian statistics. Previous measurements of the tunneling quasiparticles charge (across a quantum point contact), via shot-noise measurements, were indeed consistent with the charge of the quasiparticles being e/4. The large scattering of the experimental data in these measurements made the precise determination of the quasi-particle charge hard to achieve. In this talk I will present new shot noise data, which will shed some more light on the charge of tunneling quasiparticles at the í=5/2 state. |
