- Abstract: Analogue gravity enables the study of fields on curved spacetimes in the
laboratory. There are numerous experimental platforms in which amplification at
the event horizon or the ergoregion has been observed. Here, we demonstrate how
optically generating a defect in a polariton microcavity enables the creation
of one- and two-dimensional, transsonic fluid flows. We show that this highly
tuneable method permits the creation of sonic horizons. Furthermore, we present
a rotating geometry akin to the water-wave bathtub vortex. These experiments
usher-in the possibility of observing stimulated as well as spontaneous
amplification by the Hawking, Penrose and Zeld'ovich effects in fluids of
light.

We discuss the potential use of analogue hydrodynamic systems towards the exploration of quantum gravitational effects.
These include possible insights into the information-loss paradox, black hole physics with Planck-scale quantum corrections, emergent gravity scenarios and the regularization of curvature singularities.
We aim at bridging the gap between the non-overlapping communities of experimentalists working with classical and quantum fluids and quantum-gravity theorists.

Quantum fields in curved spacetime exhibit a wealth of effects like Hawking radiation from black holes.
In experiments, a fluid going from sub- to supersonic speed creates an effectively curved spacetime for the acoustic field.
Control over the horizon curvature and access to the spectrum on either side demonstrates the potential of quantum fluids of light for the study of field theories.

amplification of radiation by superradiance is a universal phenomenon observed in numerous physical systems.
We demonstrate that superradiant scattering generates entanglement for different input states, including coherent states.
We numerically simulate the system to demonstrate the creation of a stable ergoregion.

We report observation of self-oscillating supersonic flows in a two-dimensional atomic superfluid.
The observed superflow appears to be modulated by quasi-periodic bursts of superluminal signals.
The presented experiment demonstrates a new method for creating supersonic flows in atomic superfluids.

Hybrid quantum systems in the ultrastrong, and even more in the deep-strong, coupling regimes can exhibit exotic physical phenomena.
We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator.
This result opens a way to experimentally explore the novel quantum-vacuum effects emerging in the deep-strong coupling regime.

We show how out-of-equilibrium physics affects the dispersion relation, and hence the emission and propagation of correlated waves.
We find that emission may be optimised by supporting the phase and density of the fluid upstream of the horizon in a regime of optical bistability.

We report on an emergent mechanism for pumping in a quantum gas coupled to an optical resonator.
Due to dissipation, the cavity field evolves between its two quadratures, each corresponding to a different centrosymmetric crystal configuration.
This self-oscillation results in a time-periodic potential analogous to that describing the transport of electrons in topological tight-binding models.

We experimentally prove the feasibility of disordered quantum walks to realize a quantum simulator that is able to model general subdiffusive phenomena.
Our experiment simulates such phenomena by means of a finely controlled insertion of various levels of disorder during the evolution of the walker.
This allows us to explore the full range of subdiffusive behaviors, ranging from anomalous Anderson localization to normal diffusion.
