Effects of the Modified Uncertainty Principle on the Inflation Parameters

TL;DR

This paper investigates how the Modified Uncertainty Principle influences early universe inflation, showing it enhances density fluctuations and tensor-to-scalar ratio in standard and Randall-Sundrum models.

Contribution

It introduces the effects of the Modified Uncertainty Principle into inflationary dynamics, extending previous models to include quantum gravitational effects.

Findings

Increased amplitude of density fluctuations due to quantum gravity

Oscillatory behavior of density fluctuations

Higher tensor-to-scalar ratio observed

Abstract

In this Letter we study the effects of the Modified Uncertainty Principle as proposed in [8] on the inflationary dynamics of the early universe in both standard and Randall-Sundrum type II scenarios. We find that the quantum gravitational effect increase the amplitude of density fluctuation, which is oscillatory in nature, with an increase in the tensor-to-scalar ratio.
