From topological to non-topological solitons: kinks, domain walls and Q-balls in a scalar field model with non-trivial vacuum manifold
Yves Brihaye, Adolfo Cisterna, Betti Hartmann +1
We consider a scalar field model with a self-interaction potential that possesses a discrete vacuum manifold. We point out that this model allows for both topological as well as no…

Minimal boson stars in 5 dimensions: classical instability and existence of ergoregions
Yves Brihaye, Betti Hartmann
We show that minimal boson stars, i.e. boson stars made out of scalar fields without self-interaction, are always classically unstable in 5 space-time dimensions. This is true for…
