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…
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…
Topological invariant for holographic Weyl-Nodal line coexisting semimetal
Xiantong Chen, Xuanting Ji, Ya-Wen Sun
The presence of a topological phase in a topological many-body system can be distinguished through the analysis of topological invariants. In the present study, the topological inv…
Entanglement entropy of particles in a perturbative scattering
Jinbo Fan, Xuanting Ji, Xi-Jun Ren
The entanglement among scattering particles in an exemplary quantum electrodynamics (QED) process is studied perturbatively. To increase the computational accuracy, we need to cons…
Holographic geometry/real-space entanglement correspondence and metric reconstruction
Xuanting Ji, Xin-Xiang Ju, Ya-Wen Sun +2
In holography, the boundary entanglement structure is believed to be encoded in the bulk geometry. In this work, we investigate the precise correspondence between the boundary real…
Topological invariant for holographic Weyl- semimetal
Xiantong Chen, Xuanting Ji, Ya-Wen Sun
The occurrence of a topological phase transition can be demonstrated by a direct observation of a change in the topological invariant. For holographic topological semimetals, a top…
Coexistence of topological semimetal states in holography
Haoqi Chu, Xuanting Ji, Ya-Wen Sun
We introduce a holographic model that exhibits a coexistence state of the Weyl semimetal and the topological nodal line state, providing us with a valuable tool to investigate the…
