(UV-complete) Emergent Matrix Cosmology

Speaker(s) / Presenter(s):
Dr. Suddhasattwa Brahma (U. Edinburgh, Higgs Ctr. Theor. Phys.)

I will review recent results, and list outstanding challenges, of deriving an emergent spacetime from a non-perturbative proposal of String Theory -- namely, the BFSS matrix model. I will show how a metric can be coarse-grained from abstract matrix degrees of freedom, and how one naturally gets a scale-invariant spectrum of primordial perturbations in this model without introducing arbitrary tunable parameters. Furthermore, I will highlight distinct cosmological signatures of this model which have the potential of distinguishing it from other early-universe paradigms.
