  The Anderson-Mott transition of disordered interacting electrons is shown to
share many physical and technical features with classical random-field systems.
A renormalization group study of an order parameter field theory for the
Anderson-Mott transition shows that random-field terms appear at one-loop
order. They lead to an upper critical dimension $d_{c}^{+}=6$ for this model.
For $d>6$ the critical behavior is mean-field like. For $d<6$ an
$\epsilon$-expansion yields exponents that coincide with those for the
random-field Ising model. Implications of these results are discussed.
