simple wikipedia describes bose-einstein condensate as a "giant matter wave." Interpretively, Bose einstein condensate is a version of matter that is all wave.
Trying to think of ways of making exotic matter (like negative energy and others) I wondered if the wave identity version of a heap of disintegrating
atoms might change a bose einstein condensate "wave' because of the new partial particles. Although i sure don't know, what if something like an antineutrino (decay product) becomes part of a large wavy wad of matter?
The thing is that you would have to have very radioactive atoms as BE condensates are only made of a few (thousand) atoms, and one or more has to decay to get the novel BE form/wave. the other thing you could do is have less radioactive atoms and have long duration of the BE condensate.
If (big if) BE condensate is actually a wave then the radioactive event might cause things like nodal superposition, interference or other things that are (kind of) new to atoms, thus generating exotic matter.
Again, as a technology the purpose is to generate new forms of exotic matter and then measure or use them.
