Fun with replicas: tripartitions in tensor networks and gravity
Geoff Penington, Michael Walter, Freek Witteveen
We introduce a new correlation measure for tripartite pure states that we call . The quantity is symmetric with respect to the subsystems , , , invariant under l…
Holographic entanglement negativity and replica symmetry breaking
Xi Dong, Xiao-Liang Qi, Michael Walter
Since the work of Ryu and Takayanagi, deep connections between quantum entanglement and spacetime geometry have been revealed. The negative eigenvalues of the partial transpose of…
Bit Threads and Holographic Monogamy
Shawn X. Cui, Patrick Hayden, Temple He +3
Bit threads provide an alternative description of holographic entanglement, replacing the Ryu-Takayanagi minimal surface with bulk curves connecting pairs of boundary points. We us…
Entanglement Wedge Reconstruction via Universal Recovery Channels
Jordan Cotler, Patrick Hayden, Geoffrey Penington +3
We apply and extend the theory of universal recovery channels from quantum information theory to address the problem of entanglement wedge reconstruction in AdS/CFT. It has recentl…
Holographic duality from random tensor networks
Patrick Hayden, Sepehr Nezami, Xiao-Liang Qi +3
Tensor networks provide a natural framework for exploring holographic duality because they obey entanglement area laws. They have been used to construct explicit toy models realizi…
Holographic entropy inequalities and gapped phases of matter
Ning Bao, ChunJun Cao, Michael Walter +1
We extend our studies of holographic entropy inequalities to gapped phases of matter. For any number of regions, we determine the linear entropy inequalities satisfied by systems i…
