Understand

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.
