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…
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…
Holographic correlation functions from wedge
Tengzhou Lai, Ya-Wen Sun, Jia Tian
In this work, we propose a novel holographic method for computing correlation functions of operators in conformal field theories. This method refines previous approaches and is spe…
