Higher Derivative Mimetic Gravity
Mohammad Ali Gorji, Seyed Ali Hosseini Mansoori, Hassan Firouzjahi
We study cosmological perturbations in mimetic gravity in the presence of classified higher derivative terms which can make the mimetic perturbations stable. We show that the quadr…

Instabilities in Mimetic Matter Perturbations
Hassan Firouzjahi, Mohammad Ali Gorji, Seyed Ali Hosseini Mansoori
We study cosmological perturbations in mimetic matter scenario with a general higher derivative function. We calculate the quadratic action and show that both the kinetic term and…
