Multi-fluid potential in the loop cosmology

Understand

The scalar field can behave like a fluid with equation of state $p_{\phi}=w\rho_{\phi}$, where $w \in [-1,1]$.

• In this Letter we derive a class of the scalar field potentials for which $w=$ const.
• Scalar field with such a potential can mimic ordinary matter, radiation, cosmic strings, etc.
• We perform our calculations in the framework of the loop cosmology with holonomy corrections.
