We present a portable Rydberg-atom-based radio frequency (RF) electric ( $E$ ) field measurement instrument (Rydberg field measurement system or RFMS). The RFMS comprises an atomic RF field probe (RFP) connected by a ruggedized fiber-optic patch cord

We investigate the time dependence of atom-light and atom-RF field interactions in Rydberg electromagnetically-induced transparency (EIT) in a room-temperature and heated vapor cell. Quantum-optical transients are observed with rapid onset and dissol

Radio reception relies on antennas for the collection of electromagnetic fields carrying information, and receiver elements for demodulation and retrieval of the transmitted information. Here, we demonstrate an atom-based receiver for AM and FM micro

We use an optical-mask technique to study the atomic density distribution in two types of optical lattices. In a two-beam lattice involving magnetic-field-induced laser cooling (MILC lattice), the measurements show, in agreement with simulations, an

Cold circular Rydberg atoms are produced and magnetically trapped. The trap is characterized by direct spatial imaging of ion distributions, ion counting, and state-selective field ionization. At room temperature, we observe about 70% of the trapped

We study cold rubidium Rydberg atoms, initially prepared in state 59D5/2, guided along a two-wire magnetic atom guide. The evolution of the atoms is driven by the combined effects of internal-state transitions and dipole forces acting on the center-o
