Vibration and acoustic noises are viewed as a drawback in switched reluctance machines (SRMs), which prohibit their widespread use in noise sensitive applications. Double-stator SRMs (DSSRMs) can be considered as a solution to this problem by incorporating an improved magnetic configuration, which ...
Efficient transduction is expected, owing to the strong coupling of the orbital excited state with an electric field or mechanical vibration50,51 in an NV center. Other possible applications include multiphoton entangled resource for quantum networks and computation52,53,54,55. In conclusion, we ...
