Query: Plasmon modes of a massive Dirac plasma, and their superlattices   We explore the collective density oscillations of a collection of charged
massive Dirac particles, in one, two and three dimensions and their one
dimensional superlattice. We calculate the long wavelength limit of the
dynamical polarization function analytically, and use the random phase
approximation to obtain the plasmon dispersion. The density dependence of the
long wavelength plasmon frequency in massive Dirac systems is found to be
different compared to systems with parabolic, and gapless Dirac dispersion. We
also calculate the long wavelength plasmon dispersion of a 1d metamaterial made
from 1d and 2d massive Dirac plasma. Our analytical results will be useful for
exploring the use of massive Dirac materials as electrostatically tunable
plasmonic metamaterials and can be experimentally verified by infrared
spectroscopy as in the case of graphene [L. Ju. et. al., Nat. Nanotechnol. 6,
630 (2011)].
