It's a rich mix that the theory of superconductivity has given us," he says, referring to concepts such as pairing and symmetry breaking as applied to topology. "All those ideas really have their deep roots in work on superconductivity and they've become dominant tools for fundamental physics.
The point that is being stressed here, and which I've repeatedly mentioned, is that it is no longer a valid point to labelled areas of study such as condensed matter physics as being "applied physics". The knowledge gained, especially on the theoretical aspect of it, is as "fundamental" as anything. It is plainly apparent here in the case of superconductivity, but it can easily be said about the physics of graphene, topological insulator, BEC-BCS crossover, etc. It is in this field where various aspects of quantum field theory comes to life with utmost clarity. It is not pure fallacy that Carver Mead would say that "... Nowhere in natural phenomena do the basic laws of physics manifest themselves with more crystalline clarity...." regarding superconductivity.
So if anyone claims that anything other than high energy/particle/astrophysics/string/etc. is merely "applied", show him/her this.
