Description
ORIGINS Guest Talk.
In this talk we will discuss how to quantify the entanglement generated in the Hawking process of a Kerr or an analog rotating black hole when the input radiation is in an arbitrary gaussian state. We will see how, when the input is a thermal state, such as CMB radiation, or thermal noise in the lab, the amount of entanglement generated between interior and exterior decreases with its temperature. We will pay special attention to the interplay between the Hawking emission and superradiance, showing how the entanglement generated between interior and exterior in the rotating case will be larger or equal than in its non-rotating couterpart, depending on the relation between the Hawking temperature and that of the thermal input.
