Domain walls on the surface of q-stars
Athanasios Prikas
We study domain-wall networks on the surface of q-stars in asymptotically flat or anti de Sitter spacetime. We provide numerical solutions for the whole phase space of the stable f…
Q-stars in scalar-tensor gravitational theories in extra dimensions
Athanasios Prikas
We present Jordan-Brans-Dicke and general scalar-tensor gravitational theory in extra dimensions in an asymptotically flat or anti de Sitter spacetime. We consider a special gravit…
Q-balls constructed of spinors in Lagrangians with SU(2) symmetry
Athanasios Prikas
In the present work we investigate the existence and stability properties of q-balls which consist of a couple of scalar fields, forming an SU(2) doublet in a Lagrangian with a glo…
EYM equations in the presence of q-stars is scalar-tensor gravitational theories
Athanasios Prikas
We study Einstein-Yang-Mills equations in the presence of a gravitating non-topological soliton field configuration consisted of a Higgs doublet, in Brans-Dicke and general scalar-…
EYM equations in the presence of q-stars
Athanasios Prikas
We study Einstein-Yang-Mills equations in the presence of gravitating non-topological soliton field configurations, of q-ball type. We produce numerical solutions, stable with resp…
Q-stars in 2+1 dimensions
Athanasios Prikas
We study q-stars with one or two scalar fields, non-abelian, and fermion-scalar q-stars in 2+1 dimensions in an anti de Sitter or flat spacetime. We fully investigate their propert…
Q-stars in extra dimensions
Athanasios Prikas
We study q-stars with global and local U(1) symmetry in extra dimensions in asymptotically anti de Sitter or flat spacetime. The behavior of the mass, radius and particle number of…
Q-stars in anti de Sitter spacetime
Athanasios Prikas
We study q-stars with various symmetries in anti de Sitter spacetime in 3+1 dimensions. Comparing with the case of flat spacetime, we find that the value of the field at the center…
Q-stars and charged q-stars
Athanasios Prikas
We present the formalism of q-stars with local or global U(1) symmetry. The equations we formulate are solved numerically and provide the main features of the soliton star. We stud…
