CHAM: a fast algorithm of modelling non-linear matter power spectrum in the sCreened HAlo Model

Understand

We present a fast numerical screened halo model algorithm (CHAM) for modeling non-linear power spectrum for the alternative models to LCDM.

• This method has three obvious advantages.
• First of all, it is not being restricted to a specific dark energy/modified gravity model.
• In principle, all of the screened scalar-tensor theories can be applied.
