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…
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…
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…
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…
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…
