Abstract
It is an intriguing problem to clarify whether the odd-frequency superconducting state can be derived from a microscopic model or not, where the pairing function has odd parity in frequency. We study the instability of even-frequency and odd-frequency pairings on the extended Hubbard model in a 2D triangular lattice, with off-site Coulomb interaction V and on-site Coulomb interaction U . By using the random phase approximation (RPA), we find that the instability of odd-frequency spin-triplet s -wave pairing can be dominant with increasing V .
