Query: Fermionic statistics in the strongly correlated limit of Density
  Functional Theory   Exact pieces of information on the adiabatic connection integrand
$W_{\lambda}[\rho]$, which allows to evaluate the exchange-correlation energy
of Kohn-Sham density functional theory, can be extracted from the leading terms
in the strong coupling limit ($\lambda\to\infty$, where $\lambda$ is the
strength of the electron-electron interaction). In this work, we first compare
the theoretical prediction for the two leading terms in the strong coupling
limit with data obtained via numerical implementation of the exact Levy
functional in the simple case of two electrons confined in one dimension,
confirming the asymptotic exactness of these two terms. We then carry out a
first study on the incorporation of the fermionic statistics at large coupling
$\lambda$, both numerical and theoretical, confirming that spin effects enter
at orders $\sim e^{-\sqrt{\lambda}}$.
