This is really at the boundaries of my comprehension of physics but it’s a remarkable achievement of Italy, Europe and international Academic institutions at large - we need them all!!!

No one ever remembers to adequately compensate for sinusoidal repleneration in the wavefunction.

#13You can't read this without thinking it's science fiction. It's amazing that we've achieved this much, even if it's at such microscopic scale.

#14Although currently still in the experimental verification stage, the use of photons to create and control supersolids has great potential for exploring breakthrough levels of quantum physics phenomena and new materials science.

#16> 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.
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 r…

This is hard for me to grasp. For example, if it bumps hard into a hard solid surface, does it shear like, say, bent metal? Or is it itself 'hard' / rigid - if that is a reasonable descriptor for something at such small scales - itself, and - despite being able to flow, with no friction, smoothly - still remain 'locked in shape' at a structural level? My real question I guess is how does a collision work here?

Is Exciton-polariton what photosynthesis captures?
Re: A Supersolid Made Using Photons
#18is this practical or some nano thing they kept floating on a ultra strong magnetic field for a brief instant? i can't parse the terms.
