Abstract:
In the first part I will talk about how to write down an action for the bosonic string which incorporates a minimum area. This is motivated by the fact that loop quantum gravity has an area operator which has a positive minimum quantum of area as its lowest eigenvalue. I will demonstrate how the resulting theory can be understood in terms of a "bimetric" action for string theory - with this being the first time anybody has presented such an actual bimetric string theory action (and not simply bimetric gravity in the context of string theory as has been discussed by other authors). I will further show that when we try to write down a string action with local gauge symmetry - as opposed to simply introducing bulk gauge fields as external fields - we are naturally led to a holographic picture at the level of the classical gauged string action (based on: https://arxiv.org/abs/2407.13807v2)
