## TL;DR

This paper explores how the generalized uncertainty principle influences cosmological models, leading to a dynamical dark energy explanation for late-time universe acceleration, and connects it to phantom and tachyon fields.

## Contribution

It introduces a modified cosmological framework incorporating the generalized uncertainty principle, deriving new equations and linking dark energy to quantum gravity effects.

## Key findings

- Modified Friedmann and Raychaudhuri equations derived
- Effective dark energy and dark matter parameters obtained
- Model shown to be equivalent to Phantom and Tachyon fields

## Abstract

We investigate the impact of the generalized uncertainty principle proposed by some approaches to quantum gravity such as string theory and doubly special relativity on the cosmology. Using generalized Poisson brackets, we obtain the modified Friedmann and Raychaudhuri equations and suggest a dynamical dark energy to explain the late time acceleration of the Universe. After considering the interaction between dark matter and dark energy, originated from the minimal length, we obtain the effective cosmological parameters and equation of state parameter for dark matter and dark energy. Finally, we show that the resulting model is equivalent to the Phantom and Tachyon fields.
