Abstract
In Chaps. 3 and 4 we have examined equilibrium and nonequilibrium features of the quantum phase transition (QPT) exhibited by the quantum Rabi model (QRM). As we have emphasized, this finite-component system QPT differs from conventional phase transitions in many-body systems as it appears without scaling up system constituents. The present chapter exploits this fact, proposing a single trapped-ion experiment in which universal features of a superradiant QPT can be examined. This chapter completes, and also complements, the previous Chaps. 3 and 4 involving the QRM.

Notes
- 1.
Note that a time-independent Rabi frequency could have been used instead. For that, one would have to tune the frequency \(\omega _{D2}=\omega _I+\Omega _{D1}\) in order to provide the required resonant terms with \(\Omega _{D1}\sigma _x/2\).
