Four coupled SYK models and Nearly AdS gravities: Phase Transitions in Traversable wormholes and in Bra-ket wormholes
Tokiro Numasawa
We study four coupled SYK models and nearly AdS gravities. In the SYK model side, we construct a model that couples two copies of two coupled SYK models. In nearly AdS grav…

Chaos exponents of SYK traversable wormholes
Tomoki Nosaka, Tokiro Numasawa
In this paper we study the chaos exponent, the exponential growth rate of the out-of-time-ordered four point functions, in a two coupled SYK models which exhibits a first order pha…
