Probing Bogoliubov quasiparticles in superfluid ${}^3$He with a 'vibrating-wire like' MEMS device

M. Defoort, S. Dufresnes, S. L. Ahlstrom +11

We have measured the interaction between superfluid ${}^3$He-B and a micro-machined goalpost-shaped device at temperatures below $0.2T_c$. The measured damping follows well the the…
