I will discuss two related topics in the talk. In the first part, I will discuss a 2-dimensional SYK-like model whose moduli space consists of both a chaotic regime and corners with emergent higher-spin symmetry. This model provides a manifest realization of the widely believed connection between SYK-like models and higher-spin theories. In the second part, I will discuss a general class of coupled quantum systems that share a somewhat surprising property: their ground states approximate the thermofield double state to very good accuracy. This provides a practical way to prepare the thermofield double state.
