Abstract

Motivated by superconductivity in the newly discovered Co-based oxide, we study a single-band extended Hubbard model on a triangular lattice within the random phase approximation. We show that f-wave triplet superconductivity is stabilized in the vicinity of charge-density-wave instability. The physical origin of the realization of the f-wave triplet state is discussed.
