Journal ArticleDOI
Holographic proof of the strong subadditivity of entanglement entropy
TL;DR: In this paper, a simple geometrical proof of strong subadditivity was given for any field theory for which there is a holographically dual gravity theory, and a method has been found for computing entanglement entropies.
Journal ArticleDOI
Entanglement of purification through holographic duality
TL;DR: In this paper, the role of quantum entanglement has come to the fore, and the authors explore a quantity that connects gravity and quantum information in the light of the gauge/gravity correspondence.
Journal ArticleDOI
Holographic Fermi Surfaces and Entanglement Entropy
TL;DR: In this paper, the authors employ the logarithmic behavior of entanglement entropy to characterize the existence of Fermi surfaces and show that the specific heat always behaves anomalously.
Journal ArticleDOI
Liouville Action as Path-Integral Complexity: From Continuous Tensor Networks to AdS/CFT
Pawel Caputa,Nilay Kundu,Masamichi Miyaji,Tadashi Takayanagi,Tadashi Takayanagi,Kento Watanabe +5 more
TL;DR: In this paper, an optimization procedure for Euclidean path-integrals that evaluate CFT wave functionals in arbitrary dimensions is proposed, where the optimization is performed by minimizing certain functional, which can be interpreted as a measure of computational complexity, with respect to background metrics for the pathintegrals.
Journal ArticleDOI
Thermodynamical Property of Entanglement Entropy for Excited States
Jyotirmoy Bhattacharya,Masahiro Nozaki,Tadashi Takayanagi,Tadashi Takayanagi,Tomonori Ugajin,Tomonori Ugajin +5 more
TL;DR: It is argued that the entanglement entropy for a very small subsystem obeys a property which is analogous to the first law of thermodynamics when the authors excite the system, and this provides a universal relationship between the energy and the amount of quantum information.
