Query: Non-Perturbative Flat Direction Decay   We argue that supersymmetric flat direction vacuum expectation values can
decay non-perturbatively via preheating. Considering a toy U(1) gauge theory,
we explicitly calculate the scalar potential, in the unitary gauge, for
excitations around several flat directions. We show that the mass matrix for
the excitations has non-diagonal entries which vary with the phase of the flat
direction vacuum expectation value. Furthermore, this mass matrix has zero
eigenvalues whose eigenstates change with time. We show that these light
degrees of freedom are produced copiously in the non-perturbative decay of the
flat direction vacuum expectation value.
