Fermi ball
Hypothetical objects created in the early history of the universe / From Wikipedia, the free encyclopedia
In cosmology, Fermi balls are hypothetical objects that may have been created in the early history of the universe by spontaneous symmetry breaking. One paper has described them as "charged SLAC-bag type structures".[1] Fermi balls can be modeled as a type of non-topological soliton.
The concept is named after Enrico Fermi (see Fermion).
