# Cosmological horizons, uncertainty principle, and maximum length quantum mechanics

@article{Perivolaropoulos2017CosmologicalHU, title={Cosmological horizons, uncertainty principle, and maximum length quantum mechanics}, author={Leandros Perivolaropoulos}, journal={Physical Review D}, year={2017}, volume={95}, pages={103523} }

The cosmological particle horizon is the maximum measurable length in the Universe. The existence of such a maximum observable length scale implies a modification of the quantum uncertainty principle. Thus due to non-locality of quantum mechanics, the global properties of the Universe could produce a signature on the behaviour of local quantum systems. A Generalized Uncertainty Principle (GUP) that is consistent with the existence of such a maximum observable length scale $l_{max}$ is $\Delta x…
