Looking at Shadows of Entanglement Wedges
Yuya Kusuki, Yuki Suzuki, Tadashi Takayanagi +1
We present a new method of deriving shapes of entanglement wedges directly from CFT calculations. We point out that a reduced density matrix in holographic CFTs possesses a sharp w…
Universal Local Operator Quenches and Entanglement Entropy
Arpan Bhattacharyya, Tadashi Takayanagi, Koji Umemoto
We present a new class of local quenches described by mixed states, parameterized universally by two parameters. We compute the evolutions of entanglement entropy for both a hologr…
Entanglement Wedges from Information Metric in Conformal Field Theories
Yuki Suzuki, Tadashi Takayanagi, Koji Umemoto
We present a new method of deriving the geometry of entanglement wedges in holography directly from conformal field theories (CFTs). We analyze an information metric called the Bur…
Quantum and Classical Correlations Inside the Entanglement Wedge
Koji Umemoto
We show that the entanglement wedge cross section (EWCS) can become larger than the quantum entanglement measures such as the entanglement of formation in the AdS/CFT correspondenc…
Entanglement of Purification in Many Body Systems and Symmetry Breaking
Arpan Bhattacharyya, Alexander Jahn, Tadashi Takayanagi +1
We study the entanglement of purification (EoP), a measure of total correlation between two subsystems and , for free scalar field theory on a lattice and the transverse-fie…
Holographic Entanglement of Purification from Conformal Field Theories
Pawel Caputa, Masamichi Miyaji, Tadashi Takayanagi +1
We explore a conformal field theoretic interpretation of the holographic entanglement of purification, which is defined as the minimal area of entanglement wedge cross section. We…
Towards an Entanglement Measure for Mixed States in CFTs Based on Relative Entropy
Tadashi Takayanagi, Tomonori Ugajin, Koji Umemoto
Relative entropy of entanglement (REE) is an entanglement measure of bipartite mixed states, defined by the minimum of the relative entropy between a given mix…
Entanglement of Purification for Multipartite States and its Holographic Dual
Koji Umemoto, Yang Zhou
We introduce a new information-theoretic measure of multipartite quantum/classical correlations , by generalizing the entanglement of purification to multipartite states. We p…
Entanglement of Purification in Free Scalar Field Theories
Arpan Bhattacharyya, Tadashi Takayanagi, Koji Umemoto
We compute the entanglement of purification (EoP) in a 2d free scalar field theory with various masses. This quantity measures correlations between two subsystems and is reduced to…
Holographic Entanglement of Purification
Tadashi Takayanagi, Koji Umemoto
We study properties of the minimal cross section of entanglement wedge which connects two disconnected subsystems in holography. In particular we focus on various inequalities whic…
Holographic Entanglement Entropy on Generic Time Slices
Yuya Kusuki, Tadashi Takayanagi, Koji Umemoto
We study the holographic entanglement entropy and mutual information for Lorentz boosted subsystems. In holographic CFTs at zero and finite temperature, we find that the mutual inf…
