- Abstract: The features of topological physics can manifest in a variety of physical
systems in distinct ways. Periodically driven systems, with the advantage of
high flexibility and controllability, provide a versatile platform to simulate
many topological phenomena and may lead to novel phenomena that can not be
observed in the absence of driving. Here we investigate the influence of
realistic experimental noise on the realization of a two-level system under a
two-frequency drive that induces topologically nontrivial band structure in the
two-dimensional Floquet space. We propose a dynamical decoupling scheme that
sustains the topological phase transition overcoming the influence of
dephasing. Therefore, the proposal would facilitate the observation of
topological frequency conversion in the solid state spin system, e.g. NV center
in diamond.

We study a central spin that is quasiperiodically driven by two incommensurate frequencies, and statically coupled to $N-1$ surrounding spins.
In the strong coupling regime, the adiabatic dynamics of the total system is readily understood to imprint on the central spin an $N$-fold enhanced topological frequency conversion.
We argue that the topological burning glass effect is induced by the non-unitary dynamics of the central spin, which locally involves the collective motion of the surrounding spins.
