Revisiting holographic codes with fractal-like boundary erasures
Abstract
In this paper we investigate the code properties of holographic fractal geometries initiated in Pastawski:2016qrs. We study reconstruction wedges in AdS3/CFT2 for black hole backgrounds, which are in qualitative agreement with the vacuum-AdS approximation using generalized entanglement entropy in Bao:2022tgv. In higher dimensions, we study reconstruction wedges for the infinite, straight strip in AdSd+1/CFTd and clarify the roles of `straight' and `infinite' in their code properties. Lastly, we comment on uberholography from the perspective of complexity transfer and one-shot holography.
