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…
