Rényi Entanglement of Purification and Half Rényi Reflected Entropy in Free Scalar Theory
Liangyu Chen
In the AdS/CFT context, the entanglement of purification (EoP, denoted as ) of CFT is conjectured to be dual to the entanglement wedge cross section (EWCS) in bulk. However,…

Subsystem entropy in 2d CFT and KdV ETH
Liangyu Chen, Anatoly Dymarsky, Jia Tian +1
We study subsystem entropy in 2d CFTs, for subsystems constituting a finite fraction of the full system. We focus on the extensive contribution, which scales linearly with the subs…

Holographic Renyi entropy of 2d CFT in KdV generalized ensemble
Liangyu Chen, Anatoly Dymarsky, Jia Tian +1
The eigenstate thermalization hypothesis (ETH) in chaotic two dimensional CFTs is subtle due to infinitely many conserved KdV charges. Previous works have demonstrated that primary…
