We attach an arbitrary number of flux tubes to each particle in non-in
teracting Bose and Fermi systems in 2D. The single-particle density ma
trices of the resulting systems of composites are calculated exactly a
t T = 0 and shown to be of the form [r\rho(1)\r'] = n delta(r,r') in t
he thermodynamic limit. Thus the rho(1) of the new systems have no inf
ormation about the ODLRO or the Fermi surface in the original systems.
