Jahn-Teller Effect Essay
We all are aware of the basic states of matter i.e. solids, liquids, gases,and plasma. But apart from these there's an entire range of alternative synthetic states of matter: Bose–Einstein condensate,neutron degenerate matter, supersolids/superfluids, etc. The difference is that these alternative states are actually lab-synthesised and don't have much significance in the real world of nature.
And now, a team of researchers at Japan's Tohoku University have claimed to synthesise an entirely new metal called the ‘Jahn-Teller-metal’- a complex crystalline material that seems an insulator, superconductor, metal and magnet all rolled into one and this strange metal might be the newest state of matter.

In simple terms, by applying or removing pressure, it's possible to alter the conductivity of actually an insulator at lesser pressures. This is why the rubidium atoms are primarily used: to apply sufficient pressure. Usually when we say adding pressure, we consider squeezing something- forcing the molecules closer together by application of force. But it's possible to do the same thing chemically,by modifying the distances between the molecules by either adding or subtracting some sort of barrier between them—adding some extra atoms.
Working
In a Jahn–Teller metal as pressure is applied,the previous insulator——becomes a metal, due to the electrically-distortions as proved in the Jahn-Teller theorem. The effect continues for a while. The molecules continue to remain in their old shapes. Hence, there is an overlap. Where the material still looks like an insulator, but the electrons also manage to jump around freely as if the material were a conductor.
Buckyballs, which are explicitly similar to other supermaterials like graphene and CNTs, are known for their superconductivity. Therefore, while combining buckyballs and rubidium, the researchers created a complex structure that seemed to conduct, insulate, and magnetize simultaneously while acting as a metal. This behaviour is far beyond what ordinary matter exhibit.
So What’s the big …show more content…
Understanding and then manufacturing high-temperature superconductors, which this weird Jahn-Teller state of matter could help researchers to design and manufacture all sorts of new things possible in computing, research, transportation, infrastructure i.e. almost everything. Discoveries of superinsulators sort of paved a way to believe that this state of matter was possible, but its successful confirmation would be a game changer for science.
Future Endeavours
The research provides important breakthroughs about high-temperature superconductivity, which has been a materials science curiosity and a long-standing physics mystery. So, it may be possible to "synthetically determine" some optimal molecular structure for high temperature superconductivity. This is serving as a strong motivation to search for newer molecular superconducting materials.
This phase transition between insulator and conductor that, until now, scientists have never seen before, and hints at the possibility of transformation of various insulating materials into super-valuable superconducting materials. And this Jahn-Teller metal does it at a relatively high TC. The relationship between the parent material, the normal state above Tc, and the interstitial pairing mechanism is a key question in understanding all unconventional
