3 New papers from the group accepted in PRL in one month.

We are happy to announce that three new papers from the group have been accepted in Physical Review Letters.

• The paper of Kevin Falque on Polariton Fluids as Quantum Field Theory Simulators on Tailored Curved Spacetimes. It can be found here. In this work, we have recreated curved spacetime in the lab using a fluid of light, mimicking conditions near black holes. By shaping how light flows, we observed key features like negative energy modes: an essential step toward testing phenomena such as Hawking radiation in a controlled setting.

• The paper of Clara Piekarski on Spin and density modes in a binary fluid of light. It can be found here. In this work, we reported the experimental observation of spin and density modes in a binary mixture of superfluids of light. A miscible Bose-Bose mixture with repulsive interactions is realized by propagating the two circular polarization components of a laser through a nonlinear hot atomic vapor in the paraxial limit. By controlling the intensity and phase of both polarizations, we selectively excite the fundamental modes of the mixture. Using a Bragg-like spectroscopy technique, we measure the dispersion relation and identify two distinct branches with different sound velocities, corresponding to the spin and density modes.

• The paper of Myrann Baker on Observation of Jones-Roberts solitons in a paraxial quantum fluid of light. It can be found here. In this work, using a fluid of light flowing through hot rubidium vapor, we observe Jones-Roberts solitons: exotic shapes born from vortex pairs morphing into waves and back again.
