Contribution

It introduces a more accurate holographic relation and applies the Debye model to derive new Friedmann equations in HL gravity.

Findings

Modified Friedmann equations derived from entropic considerations.

Equations better describe the universe's evolution.

Incorporates Debye model into gravitational framework.

Abstract

Considering the results from Ho\v{r}ava-Lifshitz (HL) theory, a more precise relation between the number of bits and area in the holographic system is proposed. With this corrected relation and Debye model, two modified Friedmann equations are derived from the Hawking temperature and the Unruh temperature separately in entropic force. These equations could be better in describing the whole evolution of the universe.
