Spinning Q-balls in the complex signum-Gordon model
نویسندگان
چکیده
Rotational excitations of compact Q-balls in the complex signum-Gordon model in 2+1 dimensions are investigated. We find that almost all such spinning Q-balls have the form of a ring of strictly finite width. In the limit of large angular momentum Mz their energy is proportional to |Mz|.

We discuss Q-balls in the complex signum-Gordon model in d-dimensional space for d = 1, 2, 3. The Q-balls have strictly finite size. Their total energy is a power-like function of the conserved U (1) charge with the exponent equal to (d + 2)(d + 3) −1. In the cases d = 1 and d = 3 explicit analytic solutions are presented.
متن کاملCharged-spinning-gravitating Q-balls
We consider the lagrangian of a self-interacting complex scalar field admitting generically Q-balls solutions. This model is extended by minimal coupling to electromagnetism and to gravity. A stationnary, axially-symmetric ansatz for the different fields is used in order to reduce the classical equations. The system of non-linear partial differential equations obtained becomes a boundary value ...

We study non-topological solitons, so called Q-balls, which carry a non-vanishing Noether charge and arise as lump solutions of self-interacting complex scalar field models. Explicit examples of new axially symmetric non-spinning Q-ball solutions that have not been studied so far are constructed numerically. These solutions can be interpreted as angular excitations of the fundamental Q-balls an...
متن کاملPerturbations of the signum-Gordon model
We investigate a perturbation of a scalar field model (called here the signum-Gordon model) with the potential V (f) = |f |. The perturbation generalizes the signum-Gordon model to the signum-Klein-Gordon model i.e. to the case V (f) = |f | − 1 2λf 2, where λ is a small parameter. Such a generalization breaks the scaling symmetry of the signum-Gordon model. In this paper we concentrate on solut...
متن کاملSpinning Q–balls in Abelian Gauge Theories with positive potentials: existence and non existence
We study the existence of cylindrically symmetric electro-magnetostatic solitary waves for a system of a nonlinear Klein–Gordon equation coupled with Maxwell’s equations in presence of a positive mass and of a nonnegative nonlinear potential. Nonexistence results are provided as well.
