Constraints on four-party entanglement in holography
Vijay Balasubramanian, William K. L. Chan, Monica Jinwoo Kang +2
We show that in pure time-reflection-symmetric holographic states several known four-party entanglement signals vanish unless the triple information is non-zero. In this sens…

Detector-based measurement-induced state updates in AdS/CFT
Vijay Balasubramanian, Esko Keski-Vakkuri, Nicola Pranzini
Conventional understandings of quantum theory hold that measurements change the state of an observed system following the Lüders update rule. Textbooks describe the application of…

Counting microstates of out-of-equilibrium black hole fluctuations
Vijay Balasubramanian, Ben Craps, Juan Hernandez +2
We construct and count the microstates of out-of-equilibrium eternal AdS black holes in which a shell carrying an order one fraction of the black hole mass is emitted from the past…
