    Upon combining dissipative and nonlinear effects in a bipartite lattice of cavity polaritons, dissipatively stabilized bulk gap solitons emerge, which create a topological interface.

    Drive engineering in optical systems can be used to stabilize new nonlinear phases in topological systems. Dissipatively stabilized gap solitons in a polariton lattice establish drive engineering as a resource for nonlinear topological photonics.

    Polaritons are quasiparticles created through the coupling of matter excitations and light. A cold-atom experiment using matter waves instead of photons reports the observation of analogues of polaritons with tunable properties and no dissipation.

    Nonlinear phononics is a method for creating transient structural changes in solids, but its effect is limited to the region of optical excitation. Now, coupling to a propagating polariton allows nonlinear phononics to drive a nonlocal response.

    Polaritons are hybrid states of light and matter that occur in a wide range of physical platforms. When a nanosphere is levitated inside an optical cavity, light can hybridize with the motion on a plane rather than along an axis, resulting in ‘vectorial’ polaritons.

    When a semiconductor is embedded inside a microcavity, infrared photons have been shown to bind electrons and holes together as excitons. This result opens the door for quantum material engineering based on light–matter interactions.

    Electrons and holes in doped quantum wells cannot form bound states from usual Coulomb interaction. However, when the system is embedded in a cavity, the exchange of photons provides an effective attraction, leading to the creation of bound excitons.

    A polariton is a hybrid excitation resulting from strong light–matter coupling. The magneto-transport measurements have now revealed the crucial role played by its electronic component.

    Flow without friction is a strange phenomenon usually seen in quantum fluids that are cooled to temperatures near absolute zero, but features of superfluidity have now been seen with polaritons at ambient conditions.

    A microcavity device operating in the strong light–matter interaction regime can produce coherent perfect absorption of photons — providing a viable system for the perfect feeding of polaritons.

    Feshbach resonances provide a powerful tool for engineering interactions in ultracold atomic gases. The strong exciton–photon coupling in semiconductor microcavities facilitates the demonstration of a polaritonic Feshbach resonance with promising implications for manipulating polariton quantum fluids.

    Faraday and Dirac constructed magnetic monopoles using the practical and mathematical tools available to them. Now physicists have engineered effective monopoles by combining modern optics with nanotechnology. Part matter and part light, these magnetic monopoles travel at unprecedented speeds.

    An analogue of a magnetic monopole is now observed in a condensed state of light–matter hybrid particles known as cavity polaritons. Spin-phase excitations of the polariton fluid are accelerated along the cavity under the influence of a magnetic field—just as if they were single magnetic charges.
