Improved Lower Bound on the Thermodynamic Pressure
of the Spin 1/2 Heisenberg Ferromagnet
(27K, TeX)

ABSTRACT.  We introduce a new stochastic representation of the
partition function of the spin 1/2 Heisenberg ferromagnet. We
express some of the relevant thermodynamic quantities
in terms of expectations of functionals of so called
random  stirrings on $\Bbb Z^d$. By use of this
representation we improve the lower bound on the
pressure  given by Conlon and Solovej in [CS2].
