- Abstract summary: We show that exciton-polariton superfluids can sustain dark-soliton molecules although the interactions are fully local.
With a novel all optical technique, we create two dark solitons and bind them to each other to form an unconventional dark-soliton molecule.

- Abstract: The general theory of dark solitons relies on repulsive interactions and
therefore predicts the impossibility to form dark-soliton bound states. One
important exception to this prediction is the observation of bound solitons in
non-local nonlinear media. Here, we report that exciton-polariton superfluids
can also sustain dark-soliton molecules although the interactions are fully
local. With a novel all optical technique, we create two dark solitons and bind
them to each other to form an unconventional dark-soliton molecule. We
demonstrate that the stability of this structure and the separation distance
between two dark-solitons is tightly connected to the driven-dissipative nature
of the polariton fluid.

This perspective outlines several linear optical effects featured by molecular polaritons arising in the collective strong light-matter coupling regime.
We show that, under these circumstances, molecular absorption within a cavity can be understood as the overlap between the polariton transmission and bare molecular absorption spectra.
We highlight the limitations of this treatment when the rates of the single-molecule processes that facilitate dark-state-to-polariton relaxation cannot be neglected.

We consider an ensemble of homonuclear diatomic molecules coupled to the two polarization directions of a Fabry-P'erot cavity.
We identify a coupling mechanism mediated simultaneously by the two perpendicular polarizations, and inducing polaritonic relaxation towards molecular rotations.
Our simulations indicate that the molecular rotational dynamics in gas-phase cavity-coupled systems can serve as a novel probe for non-radiative polaritonic decay towards the dark-states manifold.

We investigate the influence of non-unitary processes on the dark state dynamics in the Tavis--Cummings model.
Our simulations show that the rate of the pure dephasing, as well as the number of particles, has a significant influence on the dark state population.

We show how under a field increase, the hybrid polariton made of photon coupled to hybrid carriers transforms into a dipolariton made of photon coupled to direct and indirect excitons.
While the hybrid polaritons display a spectral singularity, where the eigenvalues coalesce and known as exceptional point, that depends on detuning and lifetimes, we find that the three dipolaritonic states display an anti-crossing without exceptional point.

We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state.

We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.
