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…
Long-range multipartite entanglement in holographic gapless systems
Xiantong Chen, Xuanting Ji, Xin-Xiang Ju +2
Gapless quantum systems support correlations over arbitrarily long distances, giving rise to power-law long-range entanglement. We investigate long-range entanglement at strong cou…
Detecting Topological Transitions and Anisotropy through Multipartite Entanglement in Holographic Weyl Semimetals
Xiantong Chen, Xuanting Ji, Wen-Peng Li +1
We study multipartite entanglement structures in the zero-temperature holographic Weyl semimetal, focusing on tripartite and four-partite structures. For strip regions, we compute…
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…
Multipartite entanglement characterizing topological phase transitions in holographic nodal line semimetals
Xiantong Chen, Xuanting Ji, Ya-Wen Sun
Topological states of matter are characterized by nonlocal structures that are naturally encoded in the quantum entanglement of many-body wavefunctions. Topological semimetals are…
