 Jainendra K. Jain

Jainendra K. Jain proposed describing the fractional quantum Hall effect through composite fermions: correlated electronic states represented by electrons carrying an even number of units of the magnetic flux quantum. In this effective description, important fractional electronic states correspond to filled effective Landau levels, connecting them with the integer quantum Hall effect. For instance, the electronic filling factor $1/3$ belongs to the sequence $\nu =p/(2mp+1)$ with $p=m=1$. Flux attachment here encodes many-electron correlations; it is not a claim that each electron is a tiny classical solenoid.^[ref]
