Query: Floquet topological phase in a generalized PT-symmetric lattice   We consider a driven, non-Hermitian generalization of the Aubry-Andre-Harper
(AAH) model. We show that the introduction of periodic driving allows us to
obtain fully real quasienergy spectra in configurations where the corresponding
static system has complex energy eigenvalues for any non-Hermitian degree. We
illustrate how generalized parity-time (PT) symmetry can be applied within the
Floquet formalism and show that our model's fully real quasienergy spectrum
corresponds to an unbroken symmetry. This model exhibits a Floquet topological
phase, few examples of have been found in non-Hermitian potentials.
