The invention of the maser stimulated revolutionary technologies such as lasers and atomic
clocks. Yet, realizations of masers are still limited; in particular, the physics of masers …

Optical detection of Rydberg states using electromagnetically induced transparency (EIT)
enables continuous measurement of electric fields in a confined geometry. In this paper, we …

Radio frequencies in high-frequency (HF) and very high-frequency (VHF) bands (3–300
MHz) are challenging for Rydberg atom-based detection schemes, as resonant detection …

We have observed Stückelberg oscillations in the dipole-dipole interaction between
Rydberg atoms with an externally applied radio-frequency field. The oscillating rf field brings …

The radio-frequency modulated electromagnetically induced transparency (EIT) in a ladder
three-level system with Rydberg state is studied. Under the influence of a fast radio …

The giant electro-optical response of Rydberg atoms manifests itself in the emergence of
sidebands in the Rydberg excitation spectrum if the atom is exposed to a radio-frequency …

Radio-frequency (rf) fields in the MHz range are used to induce resonant energy transfer
between cold Rydberg atoms in spatially separated volumes. After laser preparation of the …

Dipole-dipole interactions between helium atoms in Rydberg-Stark states with principal
quantum number n= 53 and approximately linear Stark energy shifts, resulting from induced …

In this study, we propose a circularly polarized directional resonator (CPDR) to enhance the
reception capability of circularly polarized (CP) waves by the Rydberg atomic sensor and …

Radio frequencies in the HF and VHF (3 MHz to 300 MHz) bands are challenging for
Rydberg atom-based detection schemes, as resonant detection requires exciting the atoms …
