Entropic corrections to Friedmann equations and bouncing universe due to the zero-point length

Understand

We employ Verlinde's entropic force scenario to extract the modified Friedmann equations by taking into account the zero-point length correction to the gravitational potential.

• Starting form the modified gravitational potential due to the zero-point length, we first find the logarithmic corrections to the entropy expression and then we derive the modified Friedman equations.
• Interestingly enough, we observe that the corrected Friedmann equations are similar to the Friedmann equations in braneworld scenario.
• In addition, from the corrected Friedmann equations, we pointed out a possible connection to the GUP principle which might have implications on the Hubble tension.
