Abstract: In this talk I will introduce a domain wall in JT gravity, which is the border of two AdS2 spacetimes with different curvatures. We will find the geometric canonical variables and a four-dimensional phase space for this system. We solve the Hamiltonian on each boundary and show that their Poisson bracket vanishes. The canonical quantization is ambiguous, but we will introduce a self-consistent quantization such that the quantum Hamiltonian on each side commutes with each other. Then, we will solve it with leading WKB approximation. In this sense, we show that the JT gravity multiverse with a domain wall is dual to an entangled state between two different SSS matrix models.
