We present the first experimental observation of the Rabi splitting of M\"ossbauer resonance lines. A radio-frequency magnetic field is tuned to induce transitions between hyperfine sublevels of the Zeeman-split excited or ground state of $^{57}\mathrm{Fe}$ nuclei. The line splitting corresponding to the Rabi flopping frequency is observed using a magnetically soft $^{57}\mathrm{FeNi}$ absorber foil of composition with almost zero magnetostriction.We present the first experimental observation of the Rabi splitting of M\"ossbauer resonance lines.

Optical control of nuclear resonant absorption: theory and experiment

Roman L. Kolesov

Modification of nuclear resonant absorption by means of laser radiation is analyzed both theoretically and experimentally. Theoretical analysis is done on the basis of four-level model of atom. This model includes both electronic and nuclear excitations. It is predicted that under coherent laser driving nuclear resonant Mossbauer absorption can be significantly modified, e.g. new Mossbauer resonances can appear, some of the existing resonances can vanish, both can be Rabi-split, broadened by laser action. In addition, it is predicted that Mossbauer absorption can be completely suppressed due to coherent population trapping. Experimental observation of laser-induced transformations of Mossbauer spectra of 57Fe2+ : MgO is accomplished. New Mossbauer lines appear with laser driving while the existing are broadened. Possible explanations of the observed changes in 57Fe2+ : MgO Mossbauer spectra are population of higher-lying electronic states of iron ion and significant modification of electronic relaxation processes due to modified Jahn-Teller interaction.Modification of nuclear resonant absorption by means of laser radiation is analyzed both theoretically and experimentally.

Dynamics of a Rabi oscillation under a pulsed perturbation

Jai Min Choi, Gee-Na Kim, D. Cho

We study how a Rabi oscillation is affected by a periodic pulsed perturbation. Unlike a continuous perturbation, which simply shifts the resonance frequency, a pulsed perturbation splits the Rabi resonance into two lines separated by the pulse repetition rate. When the perturbation integrated over one pulse is equal to $\ensuremath{\pi}$, the resonance splits into two symmetrically placed lines at \ifmmode\pm\else\textpm\fi{} half the pulse repetition rate. When it is $2\ensuremath{\pi}$, the Rabi oscillation is unaffected by the perturbation. We demonstrate these behaviors using the ground hyperfine transition of cesium atoms in a magneto-optical trap. The pulsed perturbation is introduced by a periodic magnetic field pulse. The $2\ensuremath{\pi}$ case is compared with the self-induced transparency, and its implications for optical frequency metrology using a pulsed optical trap is discussed.We study how a Rabi oscillation is affected by a periodic pulsed perturbation.
