Scientists Find Clue to High-Temperature Superconductivity in Quantum Materials

Scientists have recently discovered the underlying hidden magnetic order in the pseudogap phase of a quantum material. The peculiar phase exists immediately above the superconducting transition. The research team employed an ultracold-atom simulator. They were able to detect a hidden antiferromagnetic order even when the material lacked electrons. This is referred to as doping. This is a crucial phase in designing a novel superconductor at a higher temperature. The findings offer fresh insights into a long-standing problem related to superconductivity.

Ultracold atoms reveal hidden magnetism

According to the reports, to explore the nature of the pseudogap, the researchers employed a cold-atom simulator called the Fermi-Hubbard model. Lithium atoms were chilled to within a few degrees of absolute zero and placed in a lattice created by a laser, which simulated the behaviour of electrons in solids. The quantum gas microscope captured more than 35,000 images of the individual atoms to measure the orientation of their spins. Results indicated the existence of one common pattern of correlations among the spins as the lattice cooled, which is related to a characteristic temperature at which the pseudogap occurs, and found it to be the point at which the hidden antiferromagnetic order develops.

Spin ice and magnetic monopoles

These discoveries are reminiscent of strange occurrences found in 'spin ice' magnets. The basic structural units of spin ice crystals are frustrated tetrahedrons of magnetic atoms that do not form a traditional order. It has been observed that the reverse process of a spin creates a pair of defects that represent the south and north poles of a magnet – 'monopoles' of the material. These have actually been observed in neutron scattering experiments.

I think someone sent the link, and if so I neglected to save it in the file. Thanks! Finally getting it posted.

...the underlying hidden magnetic order in the pseudogap phase of a quantum material.

In English, please, for those of us less physics capable.

[SunkenCiv]

More often the complaint is, “the writing’s too simple”, or “journalists don’t know how to write.”

It’s all English, but it’s from physics. You’ll really enjoy this:

Thanks!

The proper place to do this is in space. It is already intensely cold and will not have to expend a lot of power to cool it to a place of superconductivity.

If you can hold it in the pseudogap will it help you to open a wormhole? To power your Alcubierre drive? To regrow lost hair? :) What is the practical application?

[SunkenCiv]

I could go for the hair thing.

[Pete from Shawnee Mission]

I understand that the theoretical downside of using the Alcubierre drive is that when you reach your destination and want to slow it down it may smash up objects in local space, rather counter productive for the destination.

I suppose opening a wormhole would also be chancy....suppose it closes and you cant reopen it, or, after reopening it might not reconnect to the same Space or Time period?? (I think this was a Star Trek plot that I am remembering....)

So, hair works for me.

Hope you survived the winds and stuff! (Good night!)

[SunkenCiv]

The winds were impressive, mostly short gusts though. No power losses here in The Boonies, I heard there were some in Grand Rapids. Rain, hail, snow... snow covered everything with a light dusting. Then there was a period of wind of perhaps ten minutes (the longest single blast AFAIK, I had music on), and when I looked again, no snow. Blew away. March the Lion keeps his own timetable.
