= Density of occupied states
{title2=$Z(E)=D(E)f(E)$}

The density of available one-particle states multiplied by their mean occupation. For equilibrium electrons, $Z(E)=D(E)f(E)$ with the <Fermi-Dirac distribution> $f$. The integral of $Z$ counts electrons; the integral of $D$ counts available states.
