Query: Dynamical symmetries of periodically-driven quantum systems and their
  spectroscopic signatures   Spatial symmetries of quantum systems leads to important effects in
spectroscopy, such as selection rules and dark states. Motivated by the
increasing strength of light-matter interaction achieved in recent experiments,
we investigate a set of dynamically-generalized symmetries for quantum systems,
which are subject to a strong periodic driving. Based on Floquet response
theory, we study rotational, particle-hole, chiral and time-reversal symmetries
and their signatures in spectroscopy, including symmetry-protected dark states
(spDS), a Floquet band selection rule (FBSR), and symmetry-induced transparency
(siT). Specifically, a dynamical rotational symmetry establishes dark state
conditions, as well as selection rules for inelastic light scattering
processes; a particle-hole symmetry introduces dark states for symmetry related
Floquet states and also a transparency effect at quasienergy crossings; chiral
symmetry and time-reversal symmetry alone do not imply dark state conditions,
but can be combined to the particle-hole symmetry. Our predictions reveal new
physical phenomena when a quantum system reaches the strong light-matter
coupling regime, important for superconducting qubits, atoms and molecules in
optical or plasmonic field cavities, and optomechanical systems.
