Cyclic universe from Loop Quantum Gravity
  We discuss how a cyclic model for the flat universe can be constructively
derived from Loop Quantum Gravity. This model has a lower bounce, at small
values of the scale factor, which shares many similarities with that of Loop
Quantum Cosmology. We find that quantum gravity corrections can be also
relevant at energy densities much smaller than the Planckian one and that they
can induce an upper bounce at large values of the scale factor.
