Superconductivity.

The recent discovery of room-temperature superconductivity was cool but required impractical pressures.

What is the future of superconductivity?

Apparently superconductivity arises from a desirable interaction of electrons and phonons... Would it be possible to nanostructure or influence a material so that phonons and electrons interact in such a way that superconductivity is achieved?

That is the mechanism in classical (low temperature) superconductivity and there is no way via that interaction to achieve room temperature, 1atm pressure, superconductivity no matter the material. The interaction strength will always be too small.

However we still do not know what is going on in High-Temperature Superconductors even decades after they were first discovered. There seems to be a different interaction mechanism at work, in fact more than one, and the effect strongly depends on materials, lattice structure and internal geometry. So it seems plausible that creating a room temperature superconductor is possible once we understand that but we haven't made any meaningful progress yet.

That sounds very cool. Are there any books or papers you could recommend?

Man I hope this shit gets figured out. It's hard to overstate how revolutionary non-pressurized RTSC would be.

For superconductivity, Ashcroft & Mermin or Kittell Solid State Physics. For papers, just use google scholar.

Not really. All the material that exists in the field is very technical. The HTS wikipedia page is probably a good place to start. It will have lots of links off that.

I know you said 1atm pressure, but the recent paper:
>Room-temperature superconductivity in a carbonaceous sulfur hydride
induced superconductivity at high pressure and noted
>"strong electron–phonon coupling to high-frequency hydrogen phonon modes".
Did the high pressure cause this strong coupling? Why can't it be engineered somehow to be even stronger?

Because the high pressure compresses the lattice making the coupling stronger. iirc theorists actually worked it out in computer simulations first before experimentalists then proved it. This is no known method to distort the lattice in such a way without extreme pressures.
