摘要

In a previous study, it was suggested that superconductivity with the parity of odd-frequency spin-singlet px-wave can be realized on a quasi-one-dimensional lattice in the Hubbard model within the random phase approximation. In order to clarify physical properties of the odd-frequency superconductivity, we calculate the density of state in the odd-frequency superconducting state with a theoretical model. We find that exotic gap structure, which has not been observed in even-frequency superconductors, can be realized in the odd-frequency superconducting state.
