Query: On nearsightedness in metallic systems for $\mathcal{O}(N)$ Density
  Functional Theory calculations: A case study on Aluminum   We investigate the locality of electronic interactions in aluminum as a
function of smearing/electronic temperature in the context of $\mathcal{O}(N)$
Density Functional Theory calculations. Specifically, we determine the
convergence in energy and atomic forces with truncation region size for
smearing of $0.001-0.15$ Ha. We find exponential convergence accompanied by a
rate that increases sub-linearly with smearing, with truncation region sizes of
$48-64$ Bohr required to achieve chemical accuracy for typical smearing values
of $0.001-0.01$ Ha. This translates to $\mathcal{O}(N)$ scaling for systems
larger than $\mathcal{O}(1000)$ atoms.
