Research Abstract

Transition metal oxides with large quasiparticle mass have two features in common : geometrical frustration and strong electron correlation. I have examined the interplay of these two effects, and have revealed that chirality-driven heavy-fermion behavior emerges in Kagome lattice Hubbard model, which is a minimal model with these two ingredients.
