Dynamically Induced Topological Inflation
  We propose an inflation model in which the inflationary era is driven by the
strong dynamics of $Sp(2)$ gauge theory. The quark condensation in the confined
phase of $Sp(2)$ gauge theory generates the inflaton potential comparable to
the energy of the thermal bath at the time of phase transition. Afterwards,
with super-Planckian global minimum, the inflation commences at a false vacuum
region lying between true vacuum regions and hence the name "topological
inflation". Featured by the huge separation between the scale of the false
vacuum ($V(0)^{1/4}\sim10^{15}{\rm GeV}$) and the global minimum
($\langle\phi\rangle\sim M_{P}$), the model can be consistent with CMB
observables without suffering from the initial condition problem. Crucially,
this is achieved without any fine-tuning of parameters in $V(\phi)$. In
addition to $Sp(2)$, this model is based on an anomaly free $Z_{6R}$ discrete
$R$ symmetry. Remarkably, while all parameters are fixed by CMB observations,
the model predicts a hierarchy of energy scales including the inflation scale,
SUSY-breaking scale, R-symmetry breaking scale, Higgsino mass and the
right-handed neutrino mass given in terms of the dynamical scale of $Sp(2)$.
