Model for the fractional quantum Hall effect problem

Abstract
A simple one-dimensional model is proposed, in which N spinless interacting fermions occupy
M>N
degenerate states on a circle. It is argued that the energy spectrum and the wavefunctions of this system strongly
resemble the spectrum and wavefunctions of 2D electrons in the lowest Landau level (the problem of the
Fractional Quantum Hall Effect). In particular, Laughlin-type wavefunctions describe ground states at filling
factors
. Within this model the complimentary wavefunction for
is found
explicitly.
