Hawking radiation is the proposed thermal black-body radiation of quantum nature emitted from a black hole. One common way to give an account of Hawking radiation is to consider a detector that follows a static trajectory in the vicinity of a black hole and interacts with the quantum field of the radiation. In the present work, we study the Hawking radiation perceived by a detector that...
Free quantum field theories on spheres can be used to model important aspects of black holes. I describe examples which were initially inspired by holography in Anti-De Sitter space and discuss some thermodynamics. I also sketch techniques to operationally test their behaviour by scattering, or by monitoring how they radiate.
The large mass of optomechanical systems make them ideal for coupling to and detect weak gravitational fields. In addition, the nonlinear dynamics of the systems offer interesting sensing advantages. In my talk, I will outline the research direction of deriving the fundamental sensing limits of these systems and consider some applications, including to searches of modified gravity theories.
In this talk I will give an overview of the work in our group, where we focus on the interface between general relativity and quantum theory at low energies. We study how quantum signatures of gravity can show in table-top experiments, novel phenomena that arise from the interplay of quantum theory and gravity, and a quantum optics approach to physics beyond the Standard Model.
