• Abstract: 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.

  We study dispersive optical nonlinearities of short pulses propagating in high number density, warm atomic vapors. We show that using fast Rabi flopping and strong Rydberg atom interactions, both in the order of gigahertz, can overcome the Doppler effect. In this regime, self-induced transparency emerges when areas of the nanosecond pulse are determined primarily by the Rydberg atom interaction.
