“…This multiple-shell structure is surely possible to be models for some phenomena, such as nuclei, Bose-Einstein condensation, and star or galaxy formations, and so on. Recently, some multi-component Q-ball solutions were studied in a vorton-like model [30] and the authors claimed at least classical their stability.…”

Coupled multi-component ℂPN models with V-shaped potentials are analyzed. It is shown that the model has solutions being combinations of compact Q-balls and Q-shells. The compact nature of solutions permits the existence of novel harbor-type solutions having the form of Q-balls sheltered by Q-shells. The relation between the energy E and Noether charge Q is discussed both analytically and numerically. The energy of the solutions behaves as E ∼ |Q|α, α < 1, i.e., as for the standard Q-ball. Furthermore, the ratio E/Q for various configurations in the multi-component model suggests that the solutions are at least classically stable.

“…Recently, NTS solutions were constructed in the theory that consists of a complex scalar field, a U(1) gauge field, and a complex Higgs scalar field with a Mexican hat potential which causes the spontaneous symmetery breaking [18][19][20] 1 . In this model, there are interesting properties: the charges carried by two scalar fields are screened each other; and NTS solutions with infinitely large mass can exist [20]. These would suggest that NTSs with astrophysical scale in this model can play important roles in cosmology.…”

“…In this paper, we consider the coupled system of two complex scalar fields and a U(1) gauge field, which is studied in Refs. [18][19][20], with Einstein gravity. The local U(1) symmetry of the system is spontaneously broken in a vacuum state where one of the scalar field has an expectation value.…”

We study spherically symmetric nontopological soliton stars (NTS stars) numerically in the coupled system of a complex scalar field, a U(1) gauge field, a complex Higgs scalar field, and Einstein gravity, where the symmetry is broken spontaneously. The gravitational mass of NTS stars is limited by a maximum mass for a fixed breaking scale, and the maximum mass increases steeply as the breaking scale decreases. In the case of the breaking scale is much less than the Planck scale, the maximum mass of NTS stars becomes the astrophysical scale, and such a star is relativistically compact so that it has the innermost stable circular orbit.

“…The additional generalization to massive gauge bosons has garnered scant attention in the literature (see, however, Refs. [12][13][14][15]) because it is a significantly more difficult system to solve, even numerically. However, given the prevalence of massive gauge bosons in the Standard Model and its extensions, it is of great phenomenological interest to investigate the effect of gauge boson masses.…”

Non-topological solitons such as Q-balls and Q-shells have been studied for scalar fields invariant under global and gauged U(1) symmetries. We generalize this frame-work to include a Proca mass for the gauge boson, which can arise either from spontaneous symmetry breaking or via the Stückelberg mechanism. A heavy (light) gauge boson leads to solitons reminiscent of the global (gauged) case, but for intermediate values these Proca solitons exhibit completely novel features such as disconnected regions of viable parameter space and Q-shells with unbounded radius. We provide numerical solutions and excellent analytic approximations for both Proca Q-balls and Q-shells. These allow us to not only demonstrate the novel features numerically, but also understand and predict their origin analytically.
