Towards a Holographic Description of Inflation and Generation of Fluctuations from Thermodynamics

Understand

Recently, Verlinde conjectured that gravity may be an entropic force, arising from thermodynamics on the holographic screen.

• We investigate the implications of the entropic force formalism for inflationary cosmology.
• We find the background dynamics of inflation can be dually described in the holographic language.
• At the perturbation level, two kinds of novel scale invariant scalar fluctuations arise from thermal fluctuations on the holographic screen.
