Abstract

In order to clarify whether the odd-frequency superconductivity can be realized or not, we study a quasi-one-dimensional triangular lattice in the Hubbard model using the random-phase approximation and the fluctuation exchange approximation. We find that odd-frequency spin-singlet p -wave pairing can be stabilized on a quasi-one-dimensional isosceles triangular lattice.
