The recently published paper Emergence of spin singlets with inhomogeneous gaps in the kagome lattice Heisenberg antiferromagnets Zn-barlowite and herbertsmithite (J. Wang et al., Nature Physics 2021) in Nature Physics is accompanied by Martin Klanjšek‘s News & Views article Singlets singled out (M. Klanjšek, Nature Physics 2021). A highly recommended read!
