Title:
A model state for the filling = 1/m composite-fermion Fermi liquid states
in a partially-occupied Landau level with periodic boundary conditions.

Abstract:
A periodic boundary condition (the torus) is the geometry of choice for explicitly representing a filled Fermi sea with a Fermi surface. Using a reformulation of the states of the quantum geometry of 2D Landau-orbit guiding-centers on the quantum plane in terms of a modular-invariant modified Weierstrass sigma function, I will describe a simple model state for the compressible composite-fermion Fermi-liquid of neutral dipolar composite fermions which appears to be essentially particle-hole symmetric at filling = 1/2.
