Magnetic resonances in atomic vapor excited by a mechanical resonator



Ying-ju Wang, Matt Eardley, Svenja A. Knappe, John Moreland, Leo W. Hollberg, John E. Kitching


We demonstrate a direct resonant interaction between the mechanical motion of a mesoscopic resonator and the spin degree of freedom of a sample of neutral atoms in the gas phase. This coupling, mediated by a magnetic particle attached to the tip of the resonator, allows the excitation of the atomic spin precession about a static magnetic field. The novel coupled atom-resonator system may enable development of low-power, high performance sensors as well as cold atom manipulation, quantum computation, and high-resolution microscopy.
