Probing quantum chaos near a wormhole throat with a circular string
Ai-chen Li, Xin-Fei Li, Xuanting Ji
We investigate whether quantum fluctuations of a circular probe string develop a quantum-chaotic response while traversing a wormhole throat. The classical circular-string embeddin…
Bipartite entanglement of the primordial Majorana during inflation
Ai-chen Li, Han-Qing Shi, Keyun Wu
We use a primordial Majorana field as a fermionic probe of quantum correlations during inflation. Working in a torsion-free FLRW spacetime, we derive the two-component Majorana mod…
Quantum Entanglement of Circular Strings as a Probe for Topologically Charged Spacetimes
Ai-chen Li, Xin-Fei Li, Xuanting Ji
Motivated by the limited understanding of entanglement entropy in non-asymptotically AdS spacetimes, we develop a framework in which a circular string is embedded as a quantum prob…
Cosmological Complexity in K-essence
Ai-chen Li, Xin-Fei Li, Ding-fang Zeng +1
We calculate the cosmological complexity under the framework of scalar curvature perturbations for a K-essence model with constant potential. In particular, the squeezed quantum st…
Complexity of non-trivial sound speed in inflation
Lei-Hua Liu, Ai-Chen Li
In this paper, we study the impact of non-trivial sound on the evolution of cosmological complexity in inflationary period. The vacuum state of curvature perturbation could be trea…
Morris-Thorne Wormhole in the Vector-Tensor theories with Abelian gauge symmetry breaking
Ai-chen Li, Xin-Fei Li
We construct an asymptotically flat Morris-Thorne wormhole solution supported by anisotropic matter fluid and a vector field which is coupled to gravity in a non-minimal way with b…
Dynamic domain wall in charged dilaton black hole spacetimes
Wu-Long Xu, Ai-Chen Li, Yong-Chang Huang
In this paper we study the dynamics of dimensional domain wall universe embedded in a dimensional charged dilaton black hole bulk with the non-asymptotically flat and no…
