Cosmology with Mimetic Matter
  We consider minimal extensions of the recently proposed Mimetic Dark Matter
and show that by introducing a potential for the mimetic non-dynamical scalar
field we can mimic nearly any gravitational properties of the normal matter. In
particular, the mimetic matter can provide us with inflaton, quintessence and
even can lead to a bouncing nonsingular universe. We also investigate the
behaviour of cosmological perturbations due to a mimetic matter. We demonstrate
that simple mimetic inflation can produce red-tilted scalar perturbations which
are largely enhanced over gravity waves.
