No One Expects the Spanish Inquisition...or Excitons!

We present another in our occasional series of amazing headlines that simply have to be shared even if 95% of the world has no idea what they mean:

"Multiple Excitons Make a Surprise Appearance in 2d Hybrid Perovskites"

Excitons are quasiparticles, or subatomic effects that aren't really subatomic particles even though they sort of act like they are. The can transport energy.

And that's about as much of the article at Physics World that I understood before my brain melted down. So 2d hybrid perovskites, as well as why excitons appearing in them is some sort of surprise, will remain for an earlier-in-the-day read at another time.

Interestingly, this is the second time in the last few months that perovskites have make an appearance on the blog, with the first coming last September in another of our amazing headline entries.
