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…
Butterflies in deformed anomalous CFT
Debarshi Basu, Mingshuai Xu
We study quantum chaos in -deformed two-dimensional conformal field theories with gravitational anomaly and their holographic dual description in t…
The holographic deformation of the CFT with gravitational anomalies
Debarshi Basu, Qiang Wen, Mingshuai Xu
We develop the holographic framework for the deformation of two-dimensional conformal field theories (CFT) with gravitational anomalies, chara…
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…
