Cosmological simulations with disformally coupled symmetron fields

Understand

We investigate statistical properties of the distribution of matter at redshift zero in disformal gravity by using N-body simulations.

• The disformal model studied here consists of a conformally coupled symmetron field with an additional exponential disformal term.
• We conduct cosmological simulations to discover the impact of the new disformal terms in the matter power spectrum, halo mass function, and radial profile of the scalar field.
• We calculated the disformal geodesic equation and the equation of motion for the scalar field.
