  A method is presented for deriving the nonrelativistic quantum hamiltonian of
a free massive fermion from the relativistic lagrangian of the
Lorentz-violating standard-model extension. It permits the extraction of terms
at arbitrary order in a Foldy-Wouthuysen expansion in inverse powers of the
mass. The quantum particle hamiltonian is obtained and its nonrelativistic
limit is given explicitly to third order.
