Weak-coupling functional renormalization-group analysis of the Hubbard model on the anisotropic triangular lattice

Shan-Wen Tsai, J. B. Marston

Motivated by experiments on the layered compounds $\kappa$-(BEDT-TTF)${}_2$X, Cs${}_2$CuCl${}_4$, and very recently Na${}_x$CoO${}_2\cdot y$H${}_2$O, we present a weak-coupling functional renormal…
