Abstract

Space is widely believed to be emergent. That is, the fundamental degrees of freedom in quantum gravity are not geometrical. Due to holographic duality, we know that large N matrix quantum mechanics are microscopic models that can lead to an emergent space. However, in general these models are difficult to solve and for this reason we don’t really understand how this emergence works. I will describe two recent approaches to solving large N matrix quantum mechanics, one uses neural networks, while the other uses a “bootstrap” approach.
