Query: Theoretical Phase diagram of unconventional alkali-doped fullerides   By constructing an effective model based on recently calculated \emph{ab
}initio bare interaction parameters, we study the phase diagram of alkali doped
fullerides as a function of temperature and internal pressure. We use a
slave-rotor mean-field approach at the weak and intermediate coupling limits
and a variational mean-field approach at the strong coupling limit, and find a
good agreement with experimental phase diagram. We explain the unified
description of the phase diagram including the proximity of s-wave
superconducting state and the Mott-insulating state, and the existence of
Jahn-Teller distorted metallic state using orbital selective physics. We ague
that the double electronic occupation of two degenerate orbitals triggers both
s-wave superconductivity and Jahn-Teller distortion. While the orbital ordering
of two electrons causes the distortion, the remaining single electron in the
third orbital causes the metal-insulator transition.
