AdS gravity, SO(2,d) gauge theory and Holography
Zhao-Long Wang, Ya-Xun Song
Inspired by the general relation between the boundary global symmetry and the bulk gauge symmetry in AdS/CFT, we reformulate the dimensional AdS gravity theory as a …
Tricritical point and solid/liquid/gas phase transition of higher dimensional AdS black hole in massive gravity
Bo Liu, Zhan-Ying Yang, Rui-Hong Yue
By considering the fifth order term of the interaction potential in massive gravity theory, we study the critical behaviors of AdS black hole in dimensional space-…
Bell inequalities violation within non-Bunch-Davies states
Jun Feng, Xiaoyang Huang, Yao-Zhong Zhang +1
We study the quantum nature of non-Bunch-Davies states in de Sitter space by evaluating CHSH inequality on a localized two-atom system. We show that quantum nonlocality can be gene…
Quantum estimation in an expanding spacetime
Xiaoyang Huang, Jun Feng, Yao-Zhong Zhang +1
We investigate the quantum estimation on the Hubble parameter of an expanding de Sitter space by quantum metrological techniques. By exploring the dynamics of a freely falling Unru…
