At last, physicists report finding the ‘fourth sign’ of superconductivity
Using an advanced investigative technique, researchers at Stanford University have found that cuprate superconductors – which become superconducting at higher temperatures than their better-known conventional counterparts – transition into this exotic state in a different way. The discovery provides new insights into the way cuprate superconductors work and eases the path to discovering a room-temperature superconductor one… Continue reading

The awesome limits of superconductors
On June 24, a press release from CERN said that scientists and engineers working on upgrading the Large Hadron Collider (LHC) had “built and operated … the most powerful electrical transmission line … to date”. The transmission line consisted of four cables – two capable of transporting 20 kA of current and two, 7 kA.… Continue reading

A stinky superconductor
The next time you smell a whiff of rot in your morning’s eggs, you might not want to throw them away. Instead, you might do better to realise what you’re smelling could be a superconductor (under the right conditions) that’s, incidentally, riled up the scientific community. The source of excitement is a paper published in… Continue reading

Superconductivity: From Feshbach to Fermi
(This post is continued from this one.) After a bit of searching on Wikipedia, I found that the fundamental philosophical underpinnings of superconductivity were to be found in a statistical concept called the Feshbach resonance. If I had to teach superconductivity to those who only knew of the phenomenon superfluously, that’s where I’d begin. So.… Continue reading
About Me
I’m a science editor and writer in India, interested in high-energy and condensed-matter physics, research misconduct, pseudoscience, science’s relationship with society, epic fantasy, open source/access/knowledge systems, H.R. Giger’s art, Goundamani’s comedy, Factorio, and most things that require a lot of time to get the hang of.
