Two-photon-excited fluorescence spectroscopy of Rb atoms in a magneto-optical trap
Alan McLean, Christian Drago, Daniel Podos +5
We report the results of two-photon-excited fluorescence (TPEF) measurements of the transition of Rb and Rb cooled i…
Universality in Ionic Three-body Systems Near an Ion-atom Feshbach Resonance
Jacek Gȩbala, Michał Tomza, José P. D'Incao
We calculate bound and scattering properties of a system of two neutral atoms and an ion near an atom-ion Feshbach resonance. Our results indicate that long-range atom-ion interact…
High-Efficiency Quantum-State Detection of ThF with Resonance-Enhanced Multiphoton Asymmetric Dissociation
Kia Boon Ng, Sun Yool Park, Anzhou Wang +7
Efficient quantum-state detection is crucial for many precision control experiments, such as the ongoing effort to probe the electron's electric dipole moment using trapped molecul…
High-fidelity quantum state control of a polar molecular ion in a cryogenic environment
Dalton Chaffee, Baruch Margulis, April Sheffield +5
We use a quantum-logic spectroscopy (QLS) protocol to control the quantum state of a CaH+ ion in a cryogenic environment, in which reduced thermal radiation extends rotational stat…
CaF+CaF interactions in the ground and excited electronic states: implications for collisional losses
Dibyendu Sardar, Marcin Gronowski, Michał Tomza +1
Accurate \textit{ab initio} potential energy surfaces are essential to understand and predict collisional outcomes in ultracold molecular systems. In this study, we explore the int…
High-Stability Single-Ion Clock with Systematic Uncertainty
Mason C. Marshall, Daniel A. Rodriguez Castillo, Willa J. Arthur-Dworschack +10
We report a single-ion optical atomic clock with fractional frequency uncertainty of and fractional frequency stability of $3.5 \times10^{-16}/\sqrt{τ/\mathrm{s…
