= Solution

The quantized fermions obey a <Clifford algebra>, $\{\widehat\psi^a,\widehat\psi^b\}=g^{ab}$. When $M$ is a <spin manifold>, they act on the spinor bundle and
$$
\boxed{\mathcal H=L^2(M,S)},
$$
the Hilbert space of square-integrable <spinor fields>. The supercharge becomes the <Dirac operator>, the Hamiltonian is one half of its square, and because $M$ is even dimensional, $(-1)^F$ is the spinor chirality operator.
