The Map of Superconductivity

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.

Bad metals making great superconductors is like an inspirational quote in itself

Thank you for making these maps, it takes subjects that are not necessarily digestible by everyone and breaks them down to where even non-physicists can understand them, all the while still being respectful of people's intelligence. Much appreciated!

Filming in the woods was a very cool idea...the greenery is pretty eye soothing...do such more often

Physics is the most beautiful, incredible and important knowledge ever created

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.

A very nice and well done quick overview over a complex field which hit the sweet spot of not to trivial to be wrong and not to complex to kick 99% of the people out very well.
One thing for the back side of the map: the magic angle of bilayer graphene.

Great video! I am a PhD student in mechanical engineering and focused in thermal energy systems and sustainability. That being said, I have zero background in this subject haha. This was super informative and easy to digest. Keep making great videos!

[KalebPeters]

Brilliant as always!

Now, to get that Nobel Prize...

[zaharazettira]

This video is underrated, you deserve more views thankyou

[emanuelc]

LK 99 coming to be the room temperature superconductor!

[celeojoel]

I like how DoS also means Density of States, one of the key things studied in superconductivity

[arcsomniac]

DFTBA! Nerdfighter here, but Anton Petrov (What Da Math?!) brought me here. Great stuff!

[최영환-gp]

I love your pictures about the map of the science series. How about making those maps not only a poster but also a mouse pad? it would be really fascinating and I'm sure that many people would like it.

[atmostud]

You are hilarious. Your dry sense of humor has to be part of your success algorithm.

[sagarpraveen-nz]

I wish YT would allow me to give a 1000 likes to each of your videos. Love them

[lumanaughty]

My Map of Quantum Physics poster is my favourite thing in my room!!

[korakys]

Might need to redefine "room temperature" superconductivity after the week Vancouver has just had, heh.

[robertschlesinger]

Excellent video. Very interesting, informative and worthwhile video. This channel's videos are a must see for all thinking persons.
