‘Negative mass’ created at Washington State University

if mass = gravity
does negative-mass = anti-gravity?

if mass is created by "spins"
does un-spinning or stopping spin = un-massing?

Negative-Mass Hydrodynamics in a Spin-Orbit–Coupled Bose-Einstein Condensate
A negative effective mass can be realized in quantum systems by engineering the dispersion relation. A powerful method is provided by spin-orbit coupling, which is currently at the center of intense research efforts. Here we measure an expanding spin-orbit coupled Bose-Einstein condensate whose dispersion features a region of negative effective mass. We observe a range of dynamical phenomena, including the breaking of parity and of Galilean covariance, dynamical instabilities, and self-trapping. The experimental findings are reproduced by a single-band Gross-Pitaevskii simulation, demonstrating that the emerging features—shock waves, soliton trains, self-trapping, etc.—originate from a modified dispersion. Our work also sheds new light on related phenomena in optical lattices, where the underlying periodic structure often complicates their interpretation.
I got lost well before "Gross-Pitaevskii "
how does this look from RS view?
