Query: Quantum Phase Transitions of the Distorted Diamond Spin Chain   The frustrated quantum spin system on the distorted diamond chain lattice
suitable for the alumoklyuchevskite is investigated using the numerical
diagonalization of finite-size clusters and the level spectroscopy analysis. It
is found that this model exhibits three quantum phases; the ferrimagnetic
phase, the spin gap one, and the gapless Tomonaga-Luttinger liquid depending on
the exchange coupling parameters. The ground state phase diagram is presented.
