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…
Nonminimal derivative coupling scalar-tensor theories: odd-parity perturbations and black hole stability
Adolfo Cisterna, Miguel Cruz, Térence Delsate +1
We derive the odd parity perturbation equation in scalar-tensor theories with a non minimal kinetic coupling sector of the general Horndeski theory, where the kinetic term is coupl…
Exact solutions in SUGRA
Adolfo Cisterna, Mokhtar Hassaïne, Julio Oliva
This letter is devoted to show that the bosonic sector of the -SUGRA in four dimensions, constructed with the F-term, admits a variety of exact and analytic soluti…
Neutron stars in general second order scalar-tensor theory: the case of non-minimal derivative coupling
Adolfo Cisterna, Térence Delsate, Massimiliano Rinaldi
We consider the sector of Horndeski's gravity characterized by the coupling between the kinetic scalar field term and the Einstein tensor. We numerically construct neutron star con…
