A fundamental study based on the opto-magnetic resonance of Cesium atom modulated by spatial light and RF field

The light-atom interaction leads to the quantum coherence between atomic coupled states. Since 1950, the combination of resonant laser excitation and magnetic resonance has been one of the most important tools in atomic spectroscopy. The detected technology based on optical magnetic double resonance is essential to the research about atomic structure and the measurement of atomic property, element, and interaction. It also plays a crucial role in laser cooling, optical frequency standards, optical atomic magnetometry, and so on. In this seminar, based on the method of angular momentum probability surface and Floquet theory, I will introduce the transient coherent effect of the atomic alignment state in the detuned radio frequency field, reveal the multiple radio frequency photon transition driven by a strong field in the time periodic Hamiltonian and investigate the interaction between polarized atoms and fractional vortex vector beams.
