Universality and scaling in the collapse of spherically symmetric scalar fields in semiclassical loop quantum gravity

We study the universality and scaling observed by Choptuik in the collapse
of spherically symmetric massless scalar fields in the context of the
semiclassical equations that stem from loop quantum gravity. Contrary
to expectations, since the system has a characteristic length -the Planck
length-, we find criticality, self-similarity and "wiggles" in the scaling
relation, just like in classical general relativity.
