On the Coupling-Strength Growth of the Rabi Model in the Light of SUSYQM
  We consider the coupling-strength growth of the Rabi model from the point of the view of SUSYQM. We show that the Rabi model takes the supersymmetric system to the spontaneous supersymmetry breaking as its coupling strength g grows lager from the case g=0 to the case g\approx\infty. We study a kind of chirality quantum phase transition in this process.
