Abstract

We provide a holographic dual description of Milgrom's scaling associated with galactic rotation curves. Our argument is partly based on the recent entropic reinterpretation of Newton's laws of motion. We propose a duality between cold dark matter and modified Newtonian dynamics (MOND). We introduce the concept of MONDian dark matter, and discuss some of its phenomenological implications. At cluster as well as cosmological scales, the MONDian dark matter would behave as cold dark matter, but at the galactic scale, the MONDian dark matter would act as MOND.

Highlights

Cold Dark Matter with modified Newtonian dynamics (MOND) ScalingChiu Man Ho,∗ Djordje Minic,† and Y
One of the most outstanding puzzles of contemporary physics is the nature of the “missing mass” or dark matter [1]
There is a remarkable observation due to Milgrom, regarding a very successful scaling observed in the galactic rotation curves that goes by the name of modified Newtonian dynamics, or MOND [2]
