Analogous Hawking Effect: <i>S</i>-Matrix and Thermofield Dynamics

We consider the full <i>S</i>-matrix in the scattering giving rise to analogous Hawking radiation in dispersive media. We show the general structure of the scattering in the weak dispersion approximation and discuss some unnoticed features of the primary process, with a possible generali...
