What makes the Tc of monolayer FeSe on SrTiO3 so high： a sign-problem-free quantum Monte Carlo study

Monolayer FeSe films grown on SrTiO3 （STO） substrate show superconducting gap-opening temperatures （Tc） which are almost an order of magnitude higher than those of the bulk FeSe and are highest among all known Fe-based superconductors. Angle-resolved photoemission spectroscopy observed ＂replica band...
