PEE threads and bit threads in gravitational subregions of AdS
Debarshi Basu, Qiang Wen
Motivated by the kinematic-space description of gravitational subregions \cite{Basu:2026hbg}, we allow partial entanglement entropy (PEE) threads to be sourced not only from the as…
PEE threads and bit-threads in BTZ black brane and finite-cutoff AdS
Debarshi Basu, Ashish Chandra, Qiang Wen
We develop PEE thread flows for the planar BTZ black brane and finite-cutoff holography. Exact geodesic-distance kernels define source-resolved PEE thread currents whose superposit…
Holography and Kinematic Space for Gravitational Sub-regions in AdS
Debarshi Basu, Qiang Wen
It is well-known in integral geometry that a maximally symmetric Riemannian manifold, such as a static slice of vacuum AdS spacetime, can be perfectly covered by the geodesics in t…
Butterfly effect and -deformation
Debarshi Basu, Ashish Chandra, Qiang Wen
These notes present a comprehensive analysis of shockwave geometries in holographic settings, focusing on -deformed BTZ black holes and their exten…
