Critical Spin Liquid versus Valence Bond Glass in Triangular Lattice Organic $\kappa$-(ET)${}_2$Cu${}_2$(CN)${}_3$

Kira Riedl, Roser Valenti, Stephen M. Winter

In the quest for materials with unconventional quantum phases, the organic triangular-lattice antiferromagnet $\kappa$-(ET)${}_2$Cu${}_2$(CN)${}_3$ has been extensively discussed as a quantum…
