Holographic Mutual Information of Two Disjoint Spheres

We study quantum corrections to holographic mutual information for two disjoint spheres at a large separation by using the operator product expansion of the twist field. In the large separation limit, the holographic mutual information is vanishing at the semiclassical order, but receive quantum corrections from the fluctuations. We show that the leading contributions from the quantum fluctuations take universal forms as suggested from the boundary CFT. We find the universal behavior for the scalar, the vector, the tensor and the fermionic fields by treating these fields as free fields propagating in the fixed background and by using the 1/n prescription. In particular, for the fields with gauge symmetries, including the massless vector boson and massless graviton, we find that the gauge parts in the propagators play indispensable role in reading the leading order corrections to the bulk mutual information.Comment: 37 pages, 1 figure; significant revisions, corrected the discussions on the computations of the mutual information in CFT, conclusions unchange

Game Analysis of Government\u27s Response to Network Public Opinion

The network public opinion has brought certain challenges to the authority of the government and the control of social order. Based on the evolutionary game theory, this paper establishes the network public opinion game model of government, netizens, Internet celebrity, network media, and uses the replication dynamic equation to analyze the game process of participants. Finally, according to the evolutionary stabilization strategy, put forward relevant countermeasures to the government in dealing with network public opinion of emergencies
