The apatite family of materials holds significant potential as a key platform for advancing research on strongly correlated physics.

Further constraints on material dimensionality are expected to allow for the emergence of more physical phases. However, the thermal stability of materials tends to decrease in lower dimensions. The quasi-one-dimensional structure within apatite offers an ideal framework for doping. Using copper-doped lead apatite as the foundational structure, further doping with non-metallic elements can induce transitions between insulating, semiconducting, metallic, and even superconducting states, as well as giving rise to diverse magnetic properties. This effectively creates a veritable ’zoo of physics’.
