Abstract

We study Python’s lunch geometries in the two-dimensional Jackiw-Teitelboim model coupled to a massless scalar field in the semiclassical limit. We show that all extrema including the minimal quantum extremal surface, bulges and appetizers lie inside the horizon. We obtain fully back-reacted general bulk solutions with a massless scalar field, which can be understood as deformations of black holes. The temperatures of the left/right black holes become in general different from each other. Moreover, in the presence of both state and source deformations at the same time, the asymptotic black hole spacetime is further excited from that of the vacuum solution. We provide information-theoretic interpretation of deformed geometries including Python’s lunches, minimal quantum extremal surface and appetizers according to the entanglement wedge reconstruction hypothesis. By considering the restricted circuit complexity associated with Python’s lunch geometries and the operator complexity of the Petz map reconstructing a code space operation, we show that the observational probability of Python’s lunch degrees of freedom from the boundary is exponentially suppressed. Thus, any bulk causality violation effects related with Python’s lunch degrees are suppressed nonperturbatively.
