One of the important tasks for recent condensed matter physics is to clarify the effects of the frustration in "metals". We study Hubbard model on a frustrated lattice by using FLEX and DMFT and its extensions.

Using cluster-DMFT and quantum Monte-Carlo method, we find heavy quasiparticles near the Fermi surface at the half filling. As expected, the metallic phase is favored by introducing the frustration. More interestingly, near the Mott transition, we find that the spin fluctuations show 1-dimensional (quasi-long range correlation) behavior along each chain directions on Kagome lattice.
