Trends in Condensed Matter PhysicsFebruary 20, 2015
Figure 3: While superconductivity shows nearly steady decline, other topics such as materials show steady growth in popularity.
Grad student Michael Shulman and postdoc Marc Warner survey the state of condensed matter physics for the past nine years in a recent arXiv article. They find that the field appears to be moving increasingly away from "traditional" subjects such as superconductivity, toward those bordering with material science and engineering.
