  The discrete quantum geometric effects play an important role in dynamical
evolution in the loop quantum cosmology. These effects which are significant at
the high energies lead to the quadratic energy density modifications to the
Friedmann equation, as in the Randall-Sundrum braneworld scenarios but with a
negative sign. We investigate the scalar field dynamics in this scenario and
show the existence of a phase of super-inflation independent of the inverse
scale factor modifications as found earlier. In this regime the scalar field
mimics the dynamics of a phantom field and vice versa. We also find various
symmetries between the expanding phase, the contracting phase and the phantom
phase in the loop quantum cosmology. We then construct the scaling solutions in
the loop quantum cosmology and show their dual relationship with those of the
Randall-Sundrum cosmology.
