| Summary:
In this paper, we investigate the entanglement dynamics induced by a
composite operator, defined as the local operator evolved with the time
evolution operator constructed of the Euclidean and Lorentzian ones. The
systems under consideration are described by two-dimensional holographic
conformal field theories (2d holographic CFTs), the theories described by
gravity. Then, we find that the time ordering of Euclidean and Lorentzian time
evolutions affects the behavior of bipartite entanglement and non-local
correlation, especially their late-time ones. We also establish the relation
between entanglement entropy and energy-momentum densities. This relation
states that the late-time behaviors of bipartite entanglement and non-local
correlation strongly depend on the energy distribution. We also examine how the
decay of the quasiparticle influences the bipartite entanglement and non-local
correlation. Furthermore, we investigate the gravity dual of the systems
considered in this paper.
