论文摘要
原子级成像提供了一种可靠的工具，可以直接测量微观颗粒的运动。我们提出了一种在冷探针原子合奏中实现Rydberg原子的无损和超敏化成像的方案。相互作用增强的电磁诱导的透明度使这是可能的，从而使极狭窄的吸收倾角可增强传播。通过探针梁的传输，我们获得了具有高空间分辨率和快速响应的Rydberg原子的分布，从而确保了更精确的实时成像。与先前的相互作用增强成像技术相比，分辨率提高使我们能够仅通过调节探针呼吸谐振来准确地定位原子。这种新型的相互作用增强传输成像可以用于包含强大多体相互作用的其他不纯的系统，并且有望发展冷原子的超分辨率显微镜。
Atomic-scale imaging offers a reliable tool to directly measure the movement of microscopic particles. We present a scheme for achieving a nondestructive and ultrasensitive imaging of Rydberg atoms within an ensemble of cold probe atoms. This is made possible by the interaction-enhanced electromagnetically induced transparency at off-resonance which enables an extremely narrow absorption dip for an enhanced transmission. Through the transmission of a probe beam, we obtain the distribution of Rydberg atoms with both high spatial resolution and fast response, which ensures a more precise real-time imaging. Increased resolution compared to the prior interaction-enhanced imaging technique allows us to accurately locate the atoms by adjusting the probe detuning only. This new type of interaction-enhanced transmission imaging can be utilized to other impure systems containing strong many-body interactions, and is promising to develop super-resolution microscopy of cold atoms.
