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…
Particle Production and Krylov Complexity of Circular Strings Near Black Hole Horizons
Ai-chen Li
For an infalling circular string, we study particle production, Krylov complexity, Lanczos coefficients, and operator growth induced by quantum fluctuations. Using canonical quanti…
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…

Ai-chen Li
We use the wave-function method developed in area of quantum information to investigate the quantum circuit complexity of the small quantum fluctuations around the probe bran…
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…

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…

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…
Holographic complexity growth for a charged AdS-dilaton black holes with fixed and dynamical boundary respectively
Ai-chen Li
The holographic complexity conjectures are considered in a Einstein-Maxwell-Dilaton gravity, by using the "Complexity-Volume" proposal. Specifically, we calculate the growth rate o…
Revised parameter in Curvaton Scenario
Lei-Hua Liu, Bin Liang, Ya-Chen Zhou +3
We revise the Non-Gaussianity of canonical curvaton scenario with a generalized formalism, in which it could handle the generic potentials. In various curvaton models, the ene…
Counterterm method and thermodynamics of Hairy Black Holes in a Vector-Tensor theory with Abelian gauge symmetry breaking
Ai-chen Li
For a type of non-minimally coupled vector-tensor theories with Abelian gauge symmetry breaking in four-dimensional spacetime and correspondingly asymptotic non-AdS black hole solu…
Brane universe and holography in spacetime of charged AdS dilaton black hole
Ai-chen Li
In the background of a charged AdS dilaton black hole, we investigate the movement of a self-graviting 3-brane and relevant holographic effects as the brane move close to the AdS b…

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…
Linear Stability Analysis of Evolving Thin Shell Wormholes
Ai-chen Li, Wu-long Xu, Ding-fang Zeng
Using ideas from the brane world cosmological perturbation theory, we make linear stability analysis of dynamic thin shell wormholes constructed by cutting-and-pasting two building…

Ai-chen Li, Han-qing Shi, Ding-fang Zeng
We investigate the phase structure of a charged AdS dilaton black hole in the extended phase space which takes the cosmological constant, i.e. the AdS- parameter as pressures. T…
