• The strong coupling phase diagram of spinless fermions on an anisotropic triangular lattice at half-filling is presented. The geometry of inter-site Coulomb interactions rules the phase diagram. Unconventional charge ordered phases are detected, which are the recently reported pinball liquid and the striped chain phases. Both are induced by the quantum dynamics out of classical disordered states and afford extremely correlated metallic states and a particular domain wall-type of excitations, respectively. The disorder once killed by the quantum effect revives at finite temperature, which is discussed in terms of the organic θ-ET_2X.
