Abstract

We review some basic properties of the Fractional Quantum Hall Effect and particularly address the physics of the edge states. The chiral Luttinger liquid properties of the edges are discussed and probed experimentally using transport measurements. Shot noise measurements, which allow determination of the quasiparticle charge are also discussed. To cite this article: P. Roche et al., C. R. Physique 3 (2002) 717-732.

Résumé

Nous présentons une revue de quelques propriétés élémentaires de l'Effet Hall Quantique Fractionnaire et plus particulièrement des états de bord. Les aspects liquides chiraux de Luttinger des états de bords sont abordés et sondés expérimentalement par des mesures de transport. Les expériences de bruit de grenaille qui permettent de sonder la charge des quasiparticules sont aussi discutées. Pour citer cet article : P. Roche et al., C. R. Physique 3 (2002) 717-732.
