Abstract: The entanglement of the coupled massive scalar field in the spacetime of a Garfinkle–Horowitz–Strominger (GHS) dilaton black hole has been investigated. It is found that the entanglement does not depend on the mass of the particle and the coupling between the scalar field and the gravitational field, but it decreases as the dilaton parameter D increases. It is interesting to note that in the limit of D→M, corresponding to the case of an extreme black hole, the state has no longer distillable entanglement for any state parameter α, but the mutual information equals to a nonvanishing minimum value, which indicates that the total correlations consist of classical correlations plus bound entanglement in this limit.
