✨ Cavendish researchers have found a way to tune tiny clusters of metal nanoparticles to interact with light in surprising ways. The findings could improve non-invasive sensing technologies for #healthcare and environmental monitoring. Read the article: buff.ly/XFMKjCH
In 1974, the mathematician Douglas Hofstadter used a graphing calculator to find a fractal pattern in how electrons behave. His adviser dismissed it as numerology. The fractal, called the Hofstadter butterfly, is now known to be a real-life phenomenon. quantamagazine.org/ten-martini-pr…
Our new paper showing how molecular vibrations march in sync within plasmonic nanogaps, allowing us to engineer their coherence. Useful applications in hot electron chemistry and controlling quantum delocalization. Congrats to Fiona and team from @DeptofPhysics!

The creative process in science has its thinking tools, which we all learn eventually. Here are the 12 articles that Martin and I wrote about them, including "It takes two to think" and "A hypothesis is a liability". night-science.org/home/learn/rea… @nightsciencepod @MartinJLercher
Next in our Cavendish research theme series: #NanoPhotonics The science and application of light—at the tiniest scales imaginable. At the Cavendish, researchers are exploring how to confine light to structures over 100 times smaller than its wavelength. 🔗buff.ly/OJTmGlo
Excited to get going on a new project trying to quantify and measure quantum entanglement in molecular systems
A team of researchers at the Cavendish Laboratory, in collaboration with @UCSanDiego, has been awarded a £500,000 @EPSRC grant, plus corresponding support from @NSF, to show evidence of quantum entanglement in molecules. Read more: buff.ly/dWVv830

Good to know big corp also just uses scotch tape to secure fibers onto the holders lol (tbf theres a clamp on top of the tape)

A lens can perform the Fourier transform! 🔍 This is the 4F system: the first lens converts an image into its frequency components, and the second lens reconstructs it. By adding an aperture at the Fourier plane, we can filter out high frequencies. #Optics #Physics #b3d

If you tell me in 2015 that in 10 years we'll be talking to AI in an online FDTD simulation to help setting up the model, and run & get results within 30 seconds, I'd ask what you were smoking give me some of that cope. (not sponsored by flexcompute. The AI assistant is still…
You might think our daily life is still far from the world of quantum, atoms and electrons, but sota security CMOS camera is not that far from counting single photons (read noise ~< 0.3 electron rms). When you do it's called a quanta image sensor (QIS), and you can resolve single…
