In AdS/CFT, the partition functions of decoupled boundary systems factorize in the ``boundary” description, but not in the ``bulk” description due to gravitational configurations that connect the two systems. These space-time Wormhole explanations give rise to the so-called ``Factorizing Puzzle”. Wormhole toy models such as SYK Model/JT Gravity, by studying the averaging over ensembles of the boundary systems, get rid of the puzzle. However, a current study (arXiv:2103.16754 [hep-th]) unveils a version of the puzzle from such models by considering single elements of the ensemble with fixed fermion couplings. It pointed out that new Half-wormhole saddles, which are non-self-averaging, exist and restore the factorization of semiclassical description. In this talk, we discuss Half-wormhole solutions and their possible realizations from Black Hole singularity.
