abstract = {<p style="text-align: justify;">In this paper, we study numerical approximations of the ground states in
finite temperature density functional theory. We formulate the problem with respect
to the density matrices and justify the convergence of the finite dimensional approximations. Moreover, we provide an optimal a priori error estimate under some mild
assumptions and present some numerical experiments to support the theory.</p>},
