Laser-detected magnetic resonance spectra dressed by a radio-frequency field

Zhi Liang, Xu‐xing Geng, Pan-li Qi +4 more

We theoretically and experimentally investigate the laser-detected magnetic resonance spectra dressed by a radio-frequency magnetic field in F g = 4 of D1 line of cesium atoms. The analytical expression of the transmission spectrum for magnetic resonance dressed by a radio-frequency magnetic field is derived and has substantial agreement with the transmission spectra observed in the experiment. The theoretical prediction of the ratio of the amplitudes of the two sidebands with the detuning is basically consistent with the experimental data, which confirms the validity of the analytical expression. The separation between the two sidebands under resonance shows a highly linear proportion to the amplitude of the dressing field, which may provide a useful scheme for the measurement of radio-frequency magnetic field and magnetic imaging.

Magnetic resonance of a two-state atom dressed by a light field

Thomas E. Barrett, Nathan G. Woodard, Gregory P. Lafyatis

We discuss and demonstrate the driving of magnetic resonance transitions between members of a dressed atom doublet. A simple extension of existing dressed atom theory, describes the experimental results reasonably well. We mention low intensity, bare atom interpretations of the experiment and conclude with suggestions for further studies and possible applications.

ac electric-field-induced resonant energy transfer between cold Rydberg atoms

Joseph A. Petrus, P Bohlouli-Zanjani, J D D Martin

An oscillating electric field at 1.356 GHz was used to promote the resonant energy transfer process: 43d 5/2 + 43d 5/2 → 45p 3/2 + 41f between translationally cold 85 Rb Rydberg atoms. The ac Stark shifts due to this dressing field created degeneracies between the initial and final two-atom states of this process. The ac field strength was scanned to collect spectra which are analogous to dc electric-field-induced resonant energy transfer spectra. Different resonances were observed for different magnetic sublevels involved in the process. Compared to earlier work performed at higher frequencies, the choice of dressing frequency and structure of the spectra may be intuitively understood, by analogy with the dc field case.
