Effects of low-frequency noise in driven coherent nanodevices

We study the effect of low-frequency noise in AC driven two or many-level coherent nanodevices. Fluctuations in the properties of the device are translated in equivalent fluctuations of the driving fields. The impact on Rabi oscillations can be modulated with the detuning and minimized at resonance. In three level atoms slow noise produces qualitative changes for protocols as coherent population transfer. We propose a strategy allowing to operate at parity symmetry points, where the device is well protected against noise, despite selection rules preventing direct couplings to external fields of involved transitions.
