We propose a setup with ultracold atomic gases that can be used to make a nonrelativistic superstring in four spacetime dimensions. In particular, we consider for the creation of the superstring a fermionic atomic gas that is trapped in the core of a vortex in a Bose-Einstein condensate. We explain the required tuning of experimental parameters to achieve supersymmetry between the fermionic atoms and the bosonic modes describing the oscillations in the vortex position. Furthermore, we discuss the experimental consequences of supersymmetry.

Re: 一篇论文“Ultracold Superstrings in Atomic Boson-Fe
I have zero knowledge in condense matter.
from the abstract, it looks like they are talking about true strings, rather they are talking about large string like objects which may have bosonic and fermionic excitations. if this is the case, this is something what we will call solitonic strings.
