摘要:

在反射镜之间,电磁模式的密度不同于自由空间中的电磁模式。这改变了原子的辐射特性以及作用在原子上的光力。它在腔量子电动力学的强耦合领域有着深远的影响。对于单个原子,我们通过扫描探测激光的频率来研究原子-腔系统的各种失谐。在腔的透射过程中,原子与腔共振之间避免了交叉。在腔内偶极阱中原子的损失率中也是可见的。在正常模式的共振,占主导地位的贡献的损耗率来自偶极力的波动,这是显着增强的腔。这一结论得到了蒙特卡罗模拟的支持。

英文摘要:

Between mirrors, the density of electromagnetic modes differs from the one in free space. This changes the radiation properties of an atom as well as the light forces acting on an atom. It has profound consequences in the strong-coupling regime of cavity quantum electrodynamics. For a single atom trapped inside the cavity, we investigate the atom-cavity system by scanning the frequency of a probe laser for various atom-cavity detunings. The avoided crossing between atom and cavity resonance is visible in the transmission of the cavity. It is also visible in the loss rate of the atom from the intracavity dipole trap. On the normal-mode resonances, the dominant contribution to the loss rate originates from dipole-force fluctuations which are dramatically enhanced in the cavity. This conclusion is supported by Monte-Carlo simulations.
