We show how second-order Floquet engineering can be employed to realize systems in which many-body localization coexists with topological properties in a driven system. This allows one to implement and dynamically control a symmetry protected topologically ordered qubit even at high energies, overcoming the roadblock that the respective states cannot be prepared as ground states of nearest-neighbor Hamiltonians. Floquet engineering-the idea that a periodically driven nonequilibrium system can… Expand

Floquet Symmetry-Protected Topological Phases in Cold-Atom Systems.
TLDR
It is demonstrated that a driven transverse-field Ising model can be used to engineer complex interactions which enable the emulation of an equilibrium SPT phase and the distinction between the equilibrium and Floquet SPT phases is clarified by identifying a unique micromotion-based entanglement spectrum signature of the latter.
