On peakons and Q-balls in the baby Skyrme model
Jakub Lis
In this paper we investigate the Q-ball Ansatz in the baby Skyrme model. First, the appearance of peakons, i.e. solutions with extremely large absolute values of the second derivat…
Q-balls in the regularized signum-Gordon model
Jakub Lis
The regularized signum-Gordon potential has a smooth minimum and is linear in the modulus of the field value for higher amplitudes. The Q-ball solutions in this model are investiga…
Compact Q-balls and Q-shells in a scalar electrodynamics
H. Arodź, J. Lis
We investigate spherically symmetric non topological solitons in electrodynamics with a scalar field self interaction U ~|ψ| taken from the complex signum-Gordon model. We find Q-b…
Compact Q-balls in the complex signum-Gordon model
H. Arodź, J. Lis
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 radius. Their total energy is a power-like function of th…
