Linearized Q-Ball Perturbations
Jarah Evslin, Hui Liu, Tomasz Romańczukiewicz +3
Linearized deformations of the thick-walled (low-amplitude) (1+1)-dimensional Q-ball may be decomposed into relativistic modes, which are roughly plane waves, and also long-wavelen…
Stress stability criterion of gauged non-topological solitons in the 3+1 dimensional O(3) sigma-model
Aliaksei Mikhaliuk, Yakov Shnir
We study the energy-momentum tensor of the spherically symmetric non-topological solitons of the non-linear sigma-model with a standard kinetic term and with a symmetry brea…
Two types of boson stars in gauged -dimensional sigma-model
Jutta Kunz, Aliaksei Mikhaliuk, Yakov Shnir
We investigate boson stars in an scalar field theory with a symmetry-breaking potential. By constructing numerically spherically symmetric solutions, we demonstrate that the…
Boson stars in the gauged 3+1 dimensional sigma-model
Yakov Shnir, Aliaksei Mikhaliuk
We study regular self-gravitating non-topological soliton solutions of the gauged non-linear sigma model with the usual kinetic term and a simple symmetry breaking po…
gauged non-topological solitons in the 3+1 dimensional sigma-model
Luiz A. Ferreira, Aliaksei Mikhaliuk, Yakov Shnir
We present and study new non-topological soliton solutions in the gauged non-linear sigma model with a symmetry breaking potential in 3+1 dimensional flat space-time.…
Fermions localized on gauged Q-balls
Vladimir Dzhunushaliev, Vladimir Folomeev, Yakov Shnir
The axially symmetric gauged self-interacting Q-balls are shown to support normalizable fermionic bound state, minimally coupled to the electromagnetic field of the Q-ball.…
