Quantum sensing of radiofrequency fields using cold Rydberg atoms in a super-molasses trap
Romain Granier, Anthony El Bekai, Miguel Angel Cifuentes Marín +12
We demonstrate the quantum sensing of radiofrequency fields based on cold Rydberg atoms in a super-molasses trap, without the need for magnetic coils. Our approach combines the met…

Super-molasses returns: All optical near-resonance laser cooling and trapping of neutral atoms from background vapor
Matt Himsworth, Chester Camm, Max Carey +13
Laser cooled and trapped atoms have been the workhorse of atomic physics for the past four decades. The predominant method has been the highly versatile Magneto-Optical Trap. We de…

Laboratory confirmation and improved Accuracy of 4f and 5d energy levels of Fe II previously identified from stellar spectra
M. Ding, H. Kozuki, F. Concepcion +2
Many energy levels of singly ionised iron (Fe II, ) remain uncertain or experimentally unknown. Their identification and spectral line data are required in reliable astrophys…
