Abstract:
The quantum dynamics of fields is a frontier in our physical models for condensed matter, high energy physics and black holes. A key signature of these dynamics is the generation of entanglement. In this talk, I will show how to experimentally investigate the dynamics of entanglement when a field lives on a curved geometry, like near a black hole, allowing to test QFT predictions [1].
I will explain how to create effectively curved spacetimes with a quantum fluid of microcavity excitons-polaritons (half-light half-matter bosonic quasiparticles) and how to measure the QFT in that system [2]. I will then explain how entanglement arises due to rotational superradiance [3] and propose a way forward to measuring it.
