Given the need for negative mass, I ask the obligatory question as to whether or not this is even the smallest step towards the Alcubierre drive?

They examine a quasiparticle, so its "mass" is a number describing the behavior of an emergent excitation of the semiconductor. It's not actually mass in the sense of an elementary particle.

No. They didn't create a mass with a negative gravity potential. Unfortunately phys.org is increasing with its dubious reporting, using terms that are not entirely accurate. Likely from misunderstanding the science, not blatant lying.
