Space-time random tensor networks and holographic duality
Xiao-Liang Qi, Zhao Yang
In this paper we propose a space-time random tensor network approach for understanding holographic duality. Using tensor networks with random link projections, we define boundary t…

Butterfly velocity and bulk causal structure
Xiao-Liang Qi, Zhao Yang
The butterfly velocity was recently proposed as a characteristic velocity of chaos propagation in a local system. Compared to the Lieb-Robinson velocity that bounds the propagation…
