#2> the first experimental evidence of a supersolid phase in a driven-dissipative, non-equilibrium system using exciton-polaritons in a photonic crystal waveguide.
This is just messing with us right? Star trek level technobabble?
Just kidding, seems an exciting result, even if it flies way over my head.

Photons, held by force-fields? Sounds Trekky.

Not a single quantum in there. Could be even more advanced!

#7> The researchers created the supersolid state by condensing polaritons in a bound-in-the-continuum state within a photonic crystal waveguide. The researchers were able to achieve remarkable precision in the measurement of density modulations, hallmark of translational symmetry breaking. At the same time, they probed the local coherence of the supersolid wavefunction.
Ah yes, classic move. Clearly, by aligning the polaritons within the photonic crystal’s inverse reactive current, they’ve essentially reinvented the Retro Encabulator. It’s good to see someone finally tackling the long-standing issue of modial photon-density modulation. But I have to wonder—did they adequately compensate for sinusoidal repleneration in the supersolid wavefunction, or are we looking at another premature quantum flux leakage scenario? Call me when they’ve integrated ambifacient lunar waneshafts and a turbo-encabulated photon lattice. Until then, color me photonically unimpressed.

#8NewScientist summary, https://archive.is/b9qKH
An odd solid that can flow like a fluid has been created from light for the first time. Studying it will help researchers better understand exotic quantum states of matter. “We actually made light into a solid." ... light-based supersolids may be easier to manipulate than those previously created with atoms, which could make his team’s experiment a first step towards understanding a slew of novel and surprising types of matter.

If it can help:
- Supersolid: it's a state of matter when a system is both organised like a solid but presents superfluid-like flow without viscosity.
- Driven-dissipative: it's a qualifier for systems which are dissipative (excitations of the systems dissipate energy as heat) and driven by external fields (in this case strong electromagnetic fields are keeping the supersolid in shape). In physics, "driven" usually refers to an external influx of energy or force kept on the system.
- non-equilibrium system is what we call systems where the physics cannot be fully described by a statistical analysis of the whole over long times. These systems have transitory behaviours which are often complex before they return to equilibrium (unless they are driven away from it).
Exciton-polariton: excitons and polaritons are what we call quasiparticles. They're not particles in the sense of an electron or photon, but instead they are excitations of the collective system which look like particles. Kind of like how waves on the ocean aren't one water molecule, but a bunch of them. An exciton has no charge (it's essentially an electron and a missing electron stuck together). When an exciton couples to electromagnetic waves (photons), it can make a special type of polariton (another quasiparticle) which we call an exciton-polariton.
