Laughlin wavefunction

In condensed matter physics, the Laughlin wavefunction is an ansatz, proposed by Robert Laughlin for the ground state of a two-dimensional electron gas placed in a uniform background magnetic field in the presence of a uniform jellium background when the filling factor of the lowest Landau level is ν = 1 / n {\displaystyle \nu =1/n} where n {\displaystyle n} is an odd positive integer.
