Topological Superconductivity

https://phys.org/news/2019-08-scientists-state.html

Earlier this year a DARPA scientist patented the first room temperature superconductor, which resembles a coax cable. By inducing a nonlinear signal in the outer layer or shield of the cable, the inner core can be maintained in a superconducting state, however, this experiment created a topological superconductor, which relies on its shape to maintain superconductivity. Microsoft has been investing all their research funding into creating a topological quantum computer, which is considered the most likely path to succeed in the near future.

Both the nonlinear signal isolating a coax cable and the topological superconductor are incorporating what is sometimes described as dimension squeezing. If you force water through a hose at high pressure, you are squeezing it and the results can be very different from normal, with jets of high pressure water even being used to cut steel. While this article is of some minor interest, I posted it here in no small part to give people a heads up that superconductivity is about to invade our everyday lives.

Superconductivity usually only occurs around supercold temperatures, but quantum mechanics can treat heat as an emergent effect and, using two dimensions, you can maintain superconductivity at higher temperatures. An analogy would be that the electrons don't care so much about the heat, if they have nowhere else to go. In general, quantum mechanics suggests even the laws of nature can be swept aside at will, if the conditions are right.

 

Hello,

I am also interested in Topological Superconductivity.

Are you more interested in the Topological aspect or in the Superconductivity aspect of it?

Looking forward to a brief but fascinating discussion.
