Mixed State Entanglement for Holographic Axion Model
Yi-fei Huang, Zi-jian Shi, Chao Niu +2
We study the mixed state entanglement in a holographic axion model. We find that the holographic entanglement entropy (HEE), mutual information (MI) and entanglement of purificatio…
Holographic Subregion Complexity in General Vaidya Geometry
Yi Ling, Yuxuan Liu, Chao Niu +2
We investigate general features of the evolution of holographic subregion complexity (HSC) on Vaidya-AdS metric with a general form. The spacetime is dual to a sudden quench proces…
To be unitary-invariant or not?: a simple but non-trivial proposal for the complexity between states in quantum mechanics/field theory
Run-Qiu Yang, Yu-Sen An, Chao Niu +2
We make comments on some shortcomings of the non-unitary-invariant and non-bi-invariant complexity in quantum mechanics/field theory and argue that the unitary-invariant and bi-inv…
The Effect of Anisotropy on Holographic Entanglement Entropy and Mutual Information
Peng Liu, Chao Niu, Jian-Pin Wu
We study the effect of anisotropy on holographic entanglement entropy (HEE) and holographic mutual information (MI) in the Q-lattice model, by exploring the HEE and MI for infinite…
Complexity of Holographic Superconductors
Run-Qiu Yang, Hyun-Sik Jeong, Chao Niu +1
We study the complexity of holographic superconductors (Einstein-Maxwell-complex scalar actions in dimension) by the `complexity = volume' (CV) conjecture. First, it seems th…
