From reading the abstract, this is doing the same as reported in a 2014 paper in Phys. Rev. B by many of the same authors [1], but with a different material (K3C60). In  [1] they propose the hypothesis (hence &quot;possible&quot; in the title here) that:<p>&quot;the light establishes a transient superconducting state over only a fraction of the solid, with a lifetime of a few picoseconds&quot;<p>While certainly an interesting piece of solid-state physics, I don&#x27;t think it brings us much (if any) closer to useful-for-transporting-electricity room-temperature superconductors. (It could certainly be useful for other things though.)<p>[1] <a href="http:&#x2F;&#x2F;journals.aps.org&#x2F;prb&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevB.89.184516" rel="nofollow">http:&#x2F;&#x2F;journals.aps.org&#x2F;prb&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevB.89.184...</a><p>Edit: this group also had a similar paper in Science in 2011 that might also be of interest:
