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…
