For 10 points, identify this substance first synthesized in rubidium-87, an exotic state of matter named for a German and an Indian guy.
This substance can be produced in a so-called "cloverleaf trap". Introducing a revolving magnetic field to this substance can generate phenomena called vortices. Fischer and Schutzhold created a model of cosmic inflation using this substance. Grimm and Jin produced this substance using molecules of lithium. A one-dimensional variant of it is named for Tonks and Girardeau. Examples of materials able to produce this substance, whose state is governed by the Gross-Pitaevskii equation, include magnons, helium-4, and other particles with integer spin.
