Fictitious Magnetic Resonance by Quasi-Electrostatic Field

Abstract

We propose a new kind of spin manipulation method using a {\it fictitious} magnetic field generated by a quasi-electrostatic field. The method can be applicable to every atom with electron spins and has distinct advantages of small photon scattering rate and local addressability. By using a $\mathrm{C}{\mathrm{O}}_2$ laser as a quasi-electrostatic field, we have experimentally demonstrated the proposed method by observing the Rabi-oscillation of the ground state hyperfine spin F=1 of the cold ${}^{87}\mathrm{Rb}$ atoms and the Bose-Einstein condensate.
