| Abstract | An interacting two-dimensional electron gas in a strong magnetic field can form nontrivial topologically ordered gapped states, the fractional quantum Hall (FQH) states. The composite fermion construction was introduced by Jain to understand strongly correlated electron systems such as in FQH. While the connection between original electrons and composite fermions is unclear, composite fermion has been employed to study fractional quantum Hall (FQH) with tremendous success.
