Light propagation through an atomic vapor in the presence of a magnetic field of arbitrary direction: taking the non-orthogonality of the electric field modes into account Open
Alkali-metal atomic vapors are the foundation of an ever-growing range of applications, driven by a comprehensive understanding of their interaction with light. We focus on the case of a vapor interacting both with a low intensity laser fi…

Microwave-optical spectroscopy of Rydberg excitons in the ultrastrong driving regime Open
We study the ultrastrong driving of Rydberg excitons in Cu 2 O by a microwave field. The effect of the field is studied using optical absorption spectroscopy, and through the observation of sidebands on the transmitted laser light. A model…

Trap induced broadening in a potential hydrogen lattice clock Open
We consider the potential use of optical traps for precision measurements in atomic hydrogen (H). Using an implicit summation method, we calculate the atomic polarisability, the rates of elastic/inelastic scattering and the ionisation rate…

Detection of 3–300 MHz electric fields using Floquet sideband gaps by “Rabi matching” dressed Rydberg atoms Open
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 requires exciting atoms to extremely high energy states. We demonstrat…
