Fractionalized Fermi liquid in a frustrated Kondo lattice model
We consider Dirac electrons on the honeycomb lattice Kondo coupled to spin-1/2 degrees of freedom on the kagome lattice. The interactions between the spins are chosen along the lines of the Balents-Fisher-Girvin model that is known to host a ${\mathbb{Z}}_{2}$ spin-liquid and a ferromagnetic phase. The model is amenable to …
