Abstract / Description:The study of quantum phase transitions (see Sachdev S., Quantum Phase Transitions ( Cambridge University Press, Cambridge) 1999), which are zero-temperature phase transitions between distinct states of matter, is of current interest in research since it allows for a description of low-temperature properties based on universal relations. Here we show that the crystal green dioptase Cu6Si6O18.6H(2)O, known to he ancien Romans as he gem of Venus, has a magnetic crystal structure, formed by he Cu(II) ions, which allows for a quantum phase transition between an antiferromagnetically ordered state and a quantum spin liquid.
