Title: Stimulated Hawking effect on an Optical White-Black Hole

Abstract:

In this informal talk I’ll summarize my recent work 2107.10217 with A. Brady and D. Kranas, on which we study the Hawking effect in optical systems containing the analog of a pair white-black hole. Our work contains a synergistic combination of analytical and numerical methods. Our analytical treatment is based on techniques from quantum Gaussian information, and it provides a simple and efficient model to describe all aspects of the out state, including the entanglement between any bi-partition. These tools allow us to analyze for the first time subtle aspects of the Hawking process, like the influence that ambient thermal noise and detector inefficiencies have on the out state. We find that aspects of the Hawking effect that are of quantum origin, i.e.\ quantum entanglement, are extremely fragile to the influence of inefficiencies and noise. More importantly, we propose a protocol to amplify and observe these quantum aspects, based on seeding the process with a single-mode squeezed input. Our ideas open the door to new possibilities of experimental verification of the Hawking effect.
