The Fractional Quantum Hall Effect

چکیده
Their citation reads “ for their discovery of a new form of quantum fluid with fractionally charged excitations”. In this talk, I will try to describe this new form of quantum fluid and its fractionally charged excitations. However, since I am speaking to a general audience and the phenomenon of the fractional quantum Hall effect may not be familiar to all, I will start my talk with a brief introduction[1] to the classical Hall effect, before I start with the quantum Hall effect. The Hall effect, discovered in 1879, is simply the phenomenon that when a plate carrying an electric current is placed in a transverse magnetic field, the Lorentz force causes a potential drop perpendicular to the flow of current

Twisted Index Theory on Orbifold Symmetric Products and the Fractional Quantum Hall Effect
We extend the noncommutative geometry model of the fractional quantum Hall effect, previously developed by Mathai and the first author, to orbifold symmetric products. It retains the same properties of quantization of the Hall conductance at integer multiples of the fractional Satake orbifold Euler characteristics. We show that it also allows for interesting composite fermions and anyon represe...

Quasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible state-counting scheme, involving different assumptions on statistical correlations. Thermal activation of quasiparticle pairs and thermodynamic properties of the fractional quantum Hall liquids ne...
متن کاملIs There Another Scale in the Fractional Quantum Hall Effect?
We reanalyse theoretical considerations and experimental data, in an attempt to decide whether there is another scale in the fractional quantum Hall effect problem, in addition to the magnetic scale defined by the magnetic length a c or the cyclotron energy ¯ hω c. We then discuss possible implications of a new scale on the formulation of a theoretical model of the fractional quantum Hall effect.
