The Physical Review Letters journal has recently published a paper entitled Low-Temperature Global Symmetry Reduction in the Kagome Antiferromagnet Herbertsmithite, written by Andrej Zorko and Matjaž Gomilšek from the Solid State Physics Department, Jožef Stefan Institute. In collaboration with research groups from Croatia, USA, and France, they have observed for the first time a reduction of symmetry in herbertsmithite, a paradigm of quantum spin liquids on the kagome lattice with a theoretically predicted spin-liquid ground state. The symmetry reduction could finally provide a key clue about the nature of the ground state in this mineral. After more than a decade of intense research, this discovery provides a novel viewpoint on the enigmatic spin-liquid ground state of the kagome lattice.
