Abstract:
I will introduce the partial entanglement entropy (PEE), which is proposed to probe the entanglement fine structure. Then I present our recent work on geometrization of PEE. On a time slice, the bulk geodesics are associated with PEEs. A bit-thread configuration naturally arises from this picture. Notably, our picture is actually related to the study of holographic entanglement entropy using kinematic space, where the weighted-PEE proposal is actually the Crofton formula in integral geometry. Finally, I will also discuss how the so-called crossing PEE relates to the geometric curvature in the context of surface/state duality.
