Magnetic Resonance in an Atomic Vapor Excited by a Mechanical Resonator



Ying-Ju Wang, Matthew Eardley, Svenja A. Knappe, John M. Moreland, Leo W. Hollberg, John Kitching


We demonstrate a direct resonant interaction between the mechanical motion of a mesoscopic resonator and the spin degrees of freedom of a sample of neutral atoms in the gas phase. This couplin, mediated by a magnetic particle attached to the tip of the miniature mechanical resonator, excites a coherent precession of the atomic spins about a static magnetic field. The novel coupled atom-resonator system may enable development of low-power, high-performance sensors, and enhance research efforts connected with the manipulation of cold atoms, quantum control, and high-resolution microscopy.
