Analysis of these systems strongly depends on their symmetries, ranging, e.g., from a U(1) group in the Jaynes-Cummings model to a Z2 symmetry in the full-fledged quantum Rabi model. In recent years, novel regimes of light-matter interactions, namely, the ultrastrong and deep-strong coupling regimes, have been attracting an increasing amount of interest. The quantum Rabi and Dicke models in these exotic regimes present new features, such as collapses and revivals of the population, bounces of photon-number wave packets, as well as the breakdown of the rotating-wave approximation. Symmetries also play an important role in these regimes and will additionally change depending on whether the few- or many-qubit systems considered have associated inhomogeneous or equal couplings to the bosonic mode. Moreover, there is a growing interest in proposing and carrying out quantum simulations of these models in quantum platforms such as trapped ions, superconducting circuits, and quantum photonics. In this Special Issue Reprint, we have gathered a series of articles related to symmetry in quantum optics models, including the quantum Rabi model and its symmetries, Floquet topological quantum states in optically driven semiconductors, the spin-boson model as a simulator of non-Markovian multiphoton Jaynes-Cummings models, parity-assisted generation of nonclassical states of light in circuit quantum electrodynamics, and quasiprobability distribution functions from fractional Fourier transforms. 610 $acircuit quantum electrodynamics 610 $adynamical mean field theory 610 $aFloquet 610 $afractional Fourier transform 610 $aglobal spectrum 610 $aintegrable systems 610 $aJaynes-Cummings model 610 $alight-matter interaction 610 $amicrowave photons 610 $amultiphoton processes 610 $an/a 610 $anon-equilibrium 610 $aquantum entanglement 610 $aquantum Rabi model 610 $aquantum simulation 610 $aquasiprobability distribution functions 610 $areconstruction of the wave function 610 $asemiconductors 610 $aspin-boson model 610 $astark-effect 610 $asuperconducting circuits 610 $atopological excitations 700 $aLamata$b Lucas$4auth$01302111 906 $aBOOK 912 $a9910367742203321 996 $aSymmetry in Quantum Optics Models$93026126 997 $aUNINA
