A room-temperature superconductor would completely change electronics and now we finally understand what makes high-temperature superconductors work at these elevated temperatures. A recent breakthrough has allowed scientists to use a special microscope to image how superconductivity forms in unconventional superconductors. This is a major step towards finding a way to make ambient pressure room temperature superconductors.

Note: One of the researchers (Shane O'Mahony) pointed out that I made a mistake and said that they used a Scanning Electron Microscope (SEM) but they used an Scanning Tunneling Microscope (STM). Very different techniques.

@@ScienceDiscussed By the way, it is my old dream to experiment with copper oxide cuprates ion-implanted with lanthanoids, but I have not yet gotten around to submitting a Pathfinder-type application for this, because the existence of an international consortium (at least 3 universities) is necessary. A Hungarian university would perhaps be involved and our foundation would be the coordinator. Does that sound interesting to you?

Thank you for putting together such an interesting and informative video. I am currently researching potential topics for a 5k word school project and superconductors seem the most interesting to me. In terms of the title, was thinking something along the lines of “feasibility and applications of high temp superconductors”. Do you think that this would be a good idea or maybe the physics is too advanced and it should be avoided since there is ongoing research? Any advice would be greatly appreciated

@ScienceDiscussed Жыл бұрын

I think you could do a school project on superconductors but it might be easier to focus on the history and uses for them. The physics itself can get complicated quickly the more you devel into them.

Love the subject, but I'm a bit biased... I'm going to say it: we do not understand high-Tc SC yet. Some click bait! The pairing mechanism could be different for different materials first of all. Also, the cuprates underlying structure have many mysteries too. They may have some interesting SC phases, which resembles a Larkin-Ovchinnikov state, where the order parameter has a density wave pattern in the absence of a magnetic field, a pair-density-wave. This is like a non-zero COM momentum for our Cooper pairs. There's alot more to understand...

@Szymoonkk Жыл бұрын

Seriously thank you, was gonna say the same. We definitely do not understand high-Tc sc. There are a lot more mysteries. For sure, presence on social media requires you to make click baits, but this does not mandate saying "We are relatively confident, that superexchange is the mechanism". That is not true, you can't be anyway near confident after one study confirms one, specific prediction. Anyway, I'm still happy that someone speaks about superconductivity on youtube.

@ScienceDiscussed Жыл бұрын

Yeah to be honest you make good points that are also raised by the authors. The results do point toward superexchange being one method of induced high tc superconductivity but there may be more. The authors also suggest that there could be mechanisms that just look the same as superexchange in their Sensing modality. Either way it is a cool result but sometimes these nuances are missing when I summarise results for a video.

Can quantum simulators solve superconductivity? I heard, standard model can be simulated on a lattice.

@ScienceDiscussed Жыл бұрын

Potentially, but we need to know what to simulate to begin with. A quantum simulator would look at interaction and what physics manifests from these. So we need to know what interactions to simulate. That is why these results are so interesting for the future.

@samanthajenkins2399 Жыл бұрын

Thanks for the video. So Super-exchange could be probed by understanding the distribution of the valance electrons around the atoms and these intermediate atoms may not be "atoms" in the conventional sense but non-nuclear attractors which occur in systems such as lithium where the electronic charge density is sparse..

Thank you that was very interesting. I can't say I understand very well even though it was explained. I am tired though. The whole quantum world is amazing and I've never heard of phonon's before. I'd love to be answering a question on a game show like pointless and give an answer to "particles ending with the suffix - on" then pretend I didn't know any, but say "I wish I had my phonon me". Sorry that's probably not very funny and joked about before but oh well! I did read an article about charge density waves. Are they a promising field for the furtherment of superconducting at room temperature? I see someone mentioned the angle of your video but it wasn't too bad. A slight adjustment maybe but not distracting for me anyway. I appreciate the research. Also, someone claims to have a room temperature superconductor but aren't being taken seriously. Is it possible to entangle the sun? I'm just wondering as that is what they say and I'm not accusing them of making it up. The quantum world is very "spooky".

@ScienceDiscussed Жыл бұрын

Glad you enjoyed the video and I enjoyed your joke. I don't know much about charge density waves so I am not sure about this one. The room temperature superconductor paper was retracted in the end. So as far as most scientists are concerned we have not proven this is possible yet.

No, electrons don't band together. Thats crazy talk. Its a crystal lattice that constructs some places where the wave function of valence electrons span a fairly long distance. You gotta cool them down enough because if the atoms wiggle around too much the channels close. Ybco has fairly big channels, but its kinda brittle. Niobium titanate is very flexible but had small channels, so you gotta cool it down to liquid helium.

I really like the information and communication style, but I’m getting really distracted by your hand movements. I think this is because it takes up so much of the frame, not that you’re gesticulating. I think it’s exaggerated by your camera setup - the upward angle puts your hands in the extreme bottom of the frame AND closer to the lens, and the wide angle lens causes distortions in this area that increase the amount of the frame taken up by your hands compounding this. If you want to reduce this effect, I would suggest trying to get the camera further from you, higher up, and potentially with a longer focal length to even things out a bit. This is a personal preference here, and I totally understand if it’s not feasible in your working space or budget or any other reason for that matter. In any case, great work, I like your content and will be subscribing!
