Phys. Rev. Lett. 98, 076805 (2007) [4 pages]e/3 Laughlin Quasiparticle Primary-Filling ν=1/3 InterferometerReceived 6 September 2006; published 15 February 2007 We report experimental realization of a quasiparticle interferometer where the entire system is in 1/3 primary fractional quantum Hall state. The interferometer consists of chiral edge channels coupled by quantum-coherent tunneling in two constrictions, thus enclosing an Aharonov-Bohm area. We observe magnetic flux and charge periods h/e and e/3, equivalent to the creation of one quasielectron in the island. Quantum theory predicts a 3h/e flux period for charge e/3, integer statistics particles. Thus, the observed periods demonstrate the anyonic braiding statistics of Laughlin quasiparticles. © 2007 The American Physical Society URL:
