In this work we study the effects of the generalized uncertainty principle (GUP) in cosmology. We start with the Friedmann-Robertson-Walker (FRW) model endowed with a scalar field. After introducing the GUP modification to the model, we solve for the quantum and classical cases. Finally we find the GUP modified Friedmann equations.

  1. Stark Energy Shifts due to Quantum Gravity in RGUP Algebra

    gr-qc 2025-05 conditional novelty 4.0 of 10

    Applying the RGUP to the Stark effect yields beta-proportional energy shifts and an upper bound beta < 10^42 on the deformation parameter.
