Probing new physics using Rydberg states of atomic hydrogen (2020)
Journal Article
Jones, M., Potvliege, R., & Spannowsky, M. (2020). Probing new physics using Rydberg states of atomic hydrogen. Physical Review Research, 2(1), Article 013244. https://doi.org/10.1103/physrevresearch.2.013244

We consider the role of high-lying Rydberg states of simple atomic systems such as 1H in setting constraints on physics beyond the standard model. We obtain highly accurate bound states energies for a hydrogen atom in the presence of an additional fo... Read More about Probing new physics using Rydberg states of atomic hydrogen.

Journal Article

We perform a comprehensive investigation of the coupling between a Rydberg-dressed atomic gas and an ultra-cold plasma. Using simultaneous time-resolved measurements of both neutral atoms and ions, we show that plasma formation occurs via a Coulomb a... Read More about Coulomb anti-blockade in a Rydberg gas.

We propose and demonstrate the laser cooling and trapping of Rydberg-dressed Sr atoms. By offresonantly coupling the excited state of a narrow (7 kHz) cooling transition to a high-lying Rydberg state, we transfer Rydberg properties such as enhanced e...

We present a quantitative model for magneto-optical traps operating on narrow transitions, where the transition linewidth and the recoil shift are comparable. We combine a quantum treatment of the light scattering process with a Monte-Carlo simulatio...

Electrometry is performed using Rydberg states to evaluate the quadratic Stark shift of the 5s2 1 S0-5s5p 3 P0 clock transition in strontium. By measuring the Stark shift of the highly excited 5s75d 1 D2 state using electromagnetically induced transp... Read More about Rydberg electrometry for optical lattice clocks.

In conventional nonlinear optics, linear quantum optics1, 2, and cavity quantum electrodynamics3, 4 to create effective photon–photon interactions photons must have, at one time, interacted with matter inside a common medium. In contrast, in Rydberg... Read More about Contactless nonlinear optics mediated by long-range Rydberg interactions.

Radiation trapping in a dense cold Rydberg gas (2017)
Journal Article

Cold atomic gases resonantly excited to Rydberg states can exhibit strong optical nonlinearity at the single-photon level. We observe that in such samples radiation trapping leads to an additional mechanism for Rydberg excitation. Conversely we demon... Read More about Radiation trapping in a dense cold Rydberg gas.

Optical frequency combs provide the clockwork to relate optical frequencies to radio frequencies. Hence, combs allow optical frequencies to be measured with respect to a radio frequency where the accuracy is limited only by the reference signal. In o...
