Pair Symmetry Conversion in Driven Multiband Superconductors

By subjecting a multiband superconductor to a time-dependent drive, even-frequency pair amplitudes can be converted to odd-frequency pair amplitudes and vice versa. In the movie below we evaluate, as a function of time, both the even-frequency and odd-frequency pairing amplitudes of a multiband superconductor driven by a time-periodic chemical potential. At generic times during the period, contributions to the odd-frequency and even-frequency pair amplitudes are non-zero. The corrections to the odd- frequency amplitudes are largest exactly when the drive vanishes and smallest exactly when the drive reaches its maximum amplitude; the corrections to the even-ω amplitudes behave in the opposite manner.
