Query: Universal driving protocol for symmetry-protected Floquet topological
  phases   Universal driving protocol for symmetry-protected Floquet topological
phasesWe propose a universal driving protocol for the realization of
symmetry-protected topological phases in $2+1$ dimensional Floquet systems. Our
proposal is based on the theoretical analysis of the possible symmetries of a
square lattice model with pairwise nearest-neighbor coupling terms. Among the
eight possible symmetry operators we identify the two relevant choices for
topological phases with either time-reversal, chiral, or particle-hole
symmetry. From the corresponding symmetry conditions on the protocol
parameters, we obtain the universal driving protocol where each of the
symmetries can be realized or broken individually. We provide specific
parameter values for the different cases, and demonstrate the existence of
symmetry-protected copropagating and counterpropagating topological boundary
states. The driving protocol especially allows us to switch between bosonic and
fermionic time-reversal symmetry, and thus between a trivial and non-trivial
symmetry-protected topological phase, through continuous variation of a
parameter.
