The Map of Superconductivity

The Map of Superconductivity poster is available here: store.dftba.com/collections/d...
Superconductivity is a fascinating property exhibited by many materials when they are cooled down to cryogenic temperatures to below a certain transition temperature. Below this temperature they lose all of their electrical resistance and they are able to conduct electricity with zero loss of energy. They also exhibit interesting magnetic effects including the total expulsion of magnetic fields from their interior due to superconducting eddy currents.
In this video I look at the different kinds of superconductors like type-I and type-II superconductors, and high temperature superconductivity, the theory behind them: Ginzberg-Lanadu theory and BCS theory,, and the applications of them in the real world which include superconducting magnets for MRI machines and particle accelerators, quantum devices like josephson junctions and S.Q.U.I.Ds for uses like quantum computing.

I just defended my dissertation on Fe-based superconductors, and I found this video incredibly useful. Understanding things on a deep technical level is completely different than being able to understand it in simple terms and communicate it easily to a general audience. Like Einstein said, if you can't explain something simply, you don't understand it well enough.

Don't limit yourself to "how thing are always done". Hang out with people from your field and outside your department. Discuss.

Nice map and I enjoy your videos. I would like to mention an additional and interesting technology made possible by superconductors. Superconductors can be used to detect light on the single photon level with great precision. These superconducting nanowire single photon detectors SNSPD work by breaking down the superconduction of a wire when a photon impinges on a superconducting wire. They are around since the early 2000s and are used in the field of quantum optics. Currently the SNSPDs are setting the gold standard for single photon detection and can achieve a near unity detection efficiency.

[@frederikthiele6715]

@@alwaysdisputin9930 Not quite, the energy of a photon is big enough to break apart Cooper pairs. Once you Setup a hot spot with a normal resistive spot heating will kick in and the entire wire becomes resistive. The resistance can be easily read out. The layout of the super conductor line is critical to get it working. www.researchgate.net/profile/Chandra-Natarajan-2/publication/224836704_Superconducting_nanowire_single-photon_detectors_Physics_and_applications/links/00b49533b7632e3570000000/Superconducting-nanowire-single-photon-detectors-Physics-and-applications.pdf?origin=publication_detail

Masterful job. I agree with your earlier assessment that its not always necessary to show the kill, but occasionally it drives home the point that wilderness living is bloody at times and food/hide procurement means killing. People need to see it done with a professional dispassion in order to to realize that there is nothing cruel about it, its just a part of the cycle of life. A predator killing prey is much messier and less humane than is a hunter dispatch, but both are thankful for what nature has provided.

[@Rhannmah]

Another future application I think could be is energy storage. If you can get electrons to circulate freely inside a superconductor with no resistance, wouldn't it be possible to let them run indefinitely, therefore storing their energy for later use?

[@drdca8263]

That seems reasonable, provided the current stays under the critical current or whatever he said? Also, I think maybe that would induce a large magnetic field? Not sure whether or not that would pose a substantial engineering problem.

Dear Dr. Walliman, I am sorry, that I have to mess up your beautiful map, but superconductivity using magnetic levitation trains have been around for quite some time, the fastest of them are currently reaching 600 km/h in Japan.

[@clearshadow213]

Thanks i am a nerd and this is well put together.

[@minecraftermad]

i was thinking that the non conventional super conduction could be the shape of the electron cloud being more "flat" in a direction so that the electrons path is seemingly shorter and less forces apply parallel to the moving direction. or it could be something to do with the harmonics of movement within the material. if for example it was easier for the electron to move in a certain direction during a period of it's spin syncing up with it's path etc. that being said i'm no physicist. your explanation of cooper pairs and why they cause superconductivity was really short and simple and better than i've gotten anywhere else so thanks for that it's what made these 2 ideas alot clearer in my head. what kind of patterns to look for. both of those theories were inspired by the directionality of super conduction in the bi-layer graphene at magic angles. also having a smooth electron surface would also explain why liquid helium has 0 friction. no extra movement into direction's tangendentials. could you test for me if 2 super conductors have less friction in their super conducting phase versus not?

[@joshuamihalow6054]

No man - it’s like this: the electron cloud is normally like a mixed-up Rubik’s Cube where all the colors are mixed up - so what you gotta do is get all the little clock-elves ( which inhabit the magnetic field around it ) to solve the Rubik Cube on each side so that the atoms are lined up… And when the sides of the Rubik’s Cube colors are together, and all the colors are lined up in a straight line the clock-elves intentions are realised which makes their spirit flow uninterrupted ! And thus you have superconductivity, no problem !

[@bryonpav]

This is amazing.
