Extending the analysis in our previous paper, we construct the entanglement thermodynamics for a massless scalar field on the Schwarzschild spacetime. Contrary to the flat case, the entanglement energy Eent turns out to be proportional to the boundary area if it is near the horizon. This peculiar behavior of Eent can be understood by the red-shift effect caused by the curved background. Combine...

It is explicitly shown that the class of algebro-geometrical (finite-gap) solutions of the Ernst equation constructed several years ago in [1] contains the solutions recently constructed by R.Meinel and G.Neugebauer [2] as a subset.

We give an explicit canonical transformation which transforms a generic chiral 2D dilaton gravity model into a free field theory.
