For all of the spin doctors out there on vortex… There is some new lingo to play with - a quasiparticle known at the “roton” which been shown to violate the 2nd Law – at least in a superfluid.
Actually – the concept is not new – simply ignored over the past few decades http://adsabs.harvard.edu/abs/1993JLTP...93..861G Here is the abstract of the newer work from Nature https://www.nature.com/articles/s41567-019-0535-3 A roton is the quantized eigenmode of a freely rotating molecule. Excitations with momenta in the linear region are commonly called phonons; those with momenta close to the minimum are called rotons. The main avenue for study of rotons has been very cold liquid helium – a superfluid. If Holmlid is correct, dense hydrogen is also a superfluid - and therefore acts as a roton. Since a roton does not decay – according to the new R&D, it should be able to give momentum to phonons and the self-regenerate. Well… if one can suspend disbelief for long enough it does … but that is kinda like the miracle drug that works mainly on rats, not humans. Jones
