Kerr-de Sitter Greybody Factors via Isomonodromy
Bruno Carneiro da Cunha, Fábio Novaes
Scattering data can be generically described in terms of monodromies. Here we obtain scattering amplitudes for conformally coupled scalar fields in Kerr-de Sitter black holes using…
On the Existence of Monodromies for the Rabi model
Bruno Carneiro da Cunha, Manuela Carvalho de Almeida, Amilcar Rabelo de Queiroz
We discuss the existence of monodromies associated with the singular points of the eigenvalue problem for the Rabi model. The complete control of the full monodromy data requires t…
Kerr Scattering Coefficients via Isomonodromy
Bruno Carneiro da Cunha, Fábio Novaes
We study the scattering of a massless scalar field in a generic Kerr background. Using a particular gauge choice based on the current conservation of the radial equation, we give a…
