We demonstrate the existence of a class of nontopological fermion string solutions. The fermion configurations exist because of a nontrivial coupling between the fermions and a real scalar field, and their long, thin regions of false vacuum are supported against collapse by the pressure of massless particles trapped in the interior, rather than by the supporting pressure given by Pauli's exclusion principle in white dwarfs and neutron stars. Our solutions, even with angular momentum, appear unstable to pertur…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
