Theory of a Competitive Spin Liquid State for Weak Mott Insulators on the Triangular Lattice
Theory of a Competitive Spin Liquid State for Weak Mott Insulators on the Triangular Lattice
We propose a novel quantum spin liquid state that can explain many of the intriguing experimental properties of the low-temperature phase of the organic spin liquid candidate materials κ-(BEDT-TTF)2Cu2(CN)3 and EtMe3Sb[Pd(dmit)2]2. This state of paired fermionic spinons preserves all symmetries of the system, and it has a gapless excitation spectrum …
