YbMgGaO 4 is a quantum spin liquid candidate that promisingly realizes the long‐sought resonating‐valence‐bond picture first proposed by P. W. Anderson on the triangular lattice, as evidenced by both the high‐ and low‐energy neutron scattering measurements, as well as other experiments. The relevant experimental and theoretical progress on YbMgGaO 4 and other triangular antiferromagnets is reviewed by Yueshing Li in article number 1900089.
