QSimFP Seminar (Quantum Black Hole Theme): "Quantum vacuum excitation of a quasi-normal mode in an analog model of black hole spacetime" by Maxime Jacquet from Laboratoire Kastler Brossel,Quantum Optics Group, Paris, France

(Recorded on 9 May 2022 - Bio & Abstract below)

The Quantum Simulator for Fundamental Physics (QSimFP) consortium, including 15 investigators from 7 UK Research Organisations and 5 International Partners was formed in 2018-2020. Funding through the Quantum Technology for Fundamental Physics initiative started in November 2020 with the project duration of 3 years and 5 months. Our programme unites the quantum-technology and fundamental-physics communities, with leading scientists from both camps now working together and focusing on common goals. https://qsimfp.org/

Bio & Abstract:
Maxime Jacquet (Laboratoire Kastler Brossel,Quantum Optics Group, Paris, France), on "Quantum vacuum excitation of a quasi-normal mode in an analog model of black hole spacetime" Biosketch: Maxime is currently leading experimental and theoretical research in analogue gravity with quantum fluids of light in the Quantum Optics group at Laboratory Kastler Brossel, Sorbonne University and CNRS, France. Abstract: Analogue gravity enables the laboratory investigation of effects of quantum field theories on curved spacetimes. The archetypal example is the parametric amplification of vacuum quantum fluctuations of the field on the curved spacetime, as in the Hawking effect (the correlated emission of waves) at the event horizon. In this talk, I will review theoretical work on the Hawking effect in transsonic, quantum fluids of microcavity polaritons [1]. Because of the driven-dissipative dynamics of the fluid, the system is out of thermal equilibrium. I will explain how this impacts correlated emission by the Hawking effect [2], and also show that dissipation may be harnessed to observe novel effects like the quantum vacuum excitation of quasi-normal modes of the acoustic field [3]. This, I will argue, opens a range of new questions pertaining to all quantum fields on black hole spacetimes beyond analogue models.
