Abstract
We investigate the low-frequency plasma modes polarized in the c-direction in two-band layered superconductors. The dynamic dielectric function ε{lunate} (ω, q) is derived at T = 0, using the generalized random-phase-approximation which is consistent with the Hartree-Fock single-particle states. It is shown that the dielectric function has two zero-points which correspond to the longitudinal plasma modes in two-band layered superconductors.
