Unified description of dark energy and dark matter in mimetic matter
  model
  The existence of dark matter and dark energy in cosmology is implied by
various observations, however, they are still unclear because they have not
been directly detected. In this Letter, an unified model of dark energy and
dark matter that can explain the evolution history of the Universe later than
inflationary era, the time evolution of the growth rate function of the matter
density contrast, the flat rotation curves of the spiral galaxies, and the
gravitational experiments in the solar system is proposed in mimetic matter
model.
