Cover Story: Collective excitations of a quantum many-body state lie at the heart of studies into strongly correlated systems. Doping a Mott insulator is a prime example, leading to a rich temperature-doping phase diagram with collective excitations, including spin liquids, charge density waves, and unconventional superconductivity. Here, we show that lead apatites contain an easy passage to traverse through a landscape containing a trivial band insulator, a Mott insulator, and a doped Mott insulator with strong spin fluctuations, an elusive and highly sought after quantum mechanical paradigm. Electrons in the band insulator are effectively represented by Fermi liquid theory as a collection of independent quasi-particles, while in the doped Mott insulator, this picture breaks down, which is yet to be understood.

Since the definitions of the two-dimensional (2D) optical absorption coefficient and photoconductivity are independent of the thickness of 2D materials, they are more suitable than the dielectric function to describe the optical properties of 2D mate...
