  By considering the quantum Oppenheimer-Snyder model in loop quantum
cosmology, a new quantum black hole model whose metric tensor is a suitably
deformed Schwarzschild one is derived. The quantum effects imply a lower bound
on the mass of the black hole produced by the collapsing dust ball. For the
case of larger masses where the event horizon does form, the maximal extension
of the spacetime and its properties are investigated. By discussing the
opposite scenario to the quantum Oppenheimer-Snyder, a quantum Swiss Cheese
model is obtained with a bubble surrounded by the quantum universe. This model
is analogous to black hole cosmology or fecund universes where the big bang is
related to a white hole. Thus our models open a new window to cosmological
phenomenology.
