Fast apparent oscillations of fundamental constants
Dionysios Antypas, Dmitry Budker, Victor V. Flambaum +3
Precision spectroscopy of atoms and molecules allows one to search for and to put stringent limits on the variation of fundamental constants. These experiments are typically interp…
Precision frequency-comb terahertz spectroscopy on pure quantum states of a single molecular ion
Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz +7
Spectroscopy is a powerful tool for studying molecules and is commonly performed on large thermal molecular ensembles that are perturbed by motional shifts and interactions with th…
Time dependence of few-body Förster interactions among ultracold Rydberg atoms
Zhimin Cheryl Liu, Nina P. Inman, Thomas J. Carroll +1
Rubidium Rydberg atoms in either -sublevel of the state can exchange energy via Stark-tuned Förster resonances, including two-, three-, and four-body dipole-dipo…
Universal methods for suppressing the light shift in atomic clocks using power modulation
V. I. Yudin, M. Yu. Basalaev, A. V. Taichenachev +8
We show that the light shift in atomic clocks can be suppressed using time variation of the interrogation field intensity. By measuring the clock output at two intensity levels, er…
Dynamic characterization of an alkali-ion battery as a source for laser-cooled atoms
J. P. McGilligan, K. R. Moore, S. Kang +5
We investigate a solid-state, reversible, alkali-ion battery (AIB) capable of regulating the density of alkali atoms in a vacuum system used for the production of laser-cooled atom…
Perturbed Field Ionization for Improved State Selectivity
Vincent C. Gregoric, Jason J. Bennett, Bianca R. Gualtieri +9
Selective field ionization is used to determine the state or distribution of states to which a Rydberg atom is excited. By evolving a small perturbation to the ramped electric fiel…
