What really happens in strongly correlated superconductors: Insights   from a quantum Monte-Carlo study of high temperature superconductivity in   FeSe films
  This is a "perspective" inspired by the forthcoming article, "What makes the $T_c$ of monolayer FeSe on SrTiO so high: a sign-problem free quantum Monte Carlo study," by Z-X. Li, F. Wang, H. Yao, and D-H. Lee, arXiv:1512.06179.
