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…

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…
