#chiral #aperiodic #monotile

I doodled a spectres tonight (image is here, tiles are on my blog post).

#Chiral (left/right-handed) molecules are crucial to biochemistry. Light can distinguish between them but interacts too weakly, and boosting with #nanophotonics is not easy because it destroys chirality of EM fields. Typical solution is to design #nanostructures with highly chiral field that makes molecules absorb circularly polarised light differently. Here we find a much stronger effect where the molecules make nanostructures absorb light differently!

Well, I can't decide on the best #terahertz stories of 2022, but I can point to the result that I most wish I had thought of doing, but somebody else got to it first. It's this one, published back in March:

This describes terahertz #circular_dichroism measurements on polycrystalline samples of various different amino acids. The data indicate the presence of #chiral terahertz #phonons in some cases. Very difficult experiments, but very impressive results!

Birthday 🎂 boy #LouisPasteur was also the first to observe #chirality and then separate crystallized #enantiomers of a #chiral compound (sodium tartrate) - with a tweezer! #chemistry

Our paper on the *anomalous* circularly polarised (CP) electroluminescence of #chiral polymer films is out now in @NaturePhotonics. This paper was led by my former PhD student Li Wan, together with @Binghai11 for the theory. A short 🧵 https://www.nature.com/articles/s41566-022-01113-9

We had some super cool demonstrations of optical rotation (the rotation of the plane of polarisation of linearly polarised light as it passes through a #chiral molecule). Here’s light twisting through sucrose and fructose! 🌀🌈 I’ll paste the tweet to avoid overloading #ScienceMastodon’s servers https://twitter.com/jesswade/status/1593358274052644871
