The
Skyrme unification, from nuclei to neutron stars
-
TThe Skyrme model is a low energy effective
field theory of strong interactions where nuclei and baryons
appear as collective excitations of pionic degrees of freedom.
Proposed by Tony Skyrme in the sixties, his ideas received
further support when it was discovered that in the limit of the
large number of colours of QCD, an effective theory of mesons
arises.
-
-
In the last years, there has been a revival of
Skyrme's ideas and new related models, some of them with BPS
bounds (topological lower energy bounds), have been proposed. It
is the aim of this talk to present one of them, namely, the BPS
Skyrme model, and to explore the nuclear world, from nuclei to
neutron stars.
