Query: Reemergeing electronic nematicity in heavily hole-doped Fe-based
  superconductors   In correlated electrons system, quantum melting of electronic crystalline
phase often gives rise to many novel electronic phases. In cuprates
superconductors, melting the Mott insulating phase with carrier doping leads to
a quantum version of liquid crystal phase, the electronic nematicity, which
breaks the rotational symmetry and exhibits a tight twist with high-temperature
superconductivity. Recently, the electronic nematicity has also been observed
in Fe-based superconductors. However, whether it shares a similar scenario with
its cuprates counterpart is still elusive. Here, by measuring nuclear magnetic
resonance in CsFe2As2, a prototypical Fe-based superconductor perceived to have
evolved from a Mott insulating phase at 3d5 configuration, we report
anisotropic quadruple broadening effect as a direct result of local rotational
symmetry breaking. For the first time, clear connection between the Mott
insulating phase and the electronic nematicity can be established and
generalized to the Fe-based superconductors. This finding would promote a
universal understanding on electronic nematicity and its relation with
high-temperature superconductivity.
