High-efficiency quantum-state detection of with resonance-enhanced multiphoton asymmetric dissociation Open
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 molecular ThF + 232 ions at JILA. While quantum-state detec…

A new bound on the electron's electric dipole moment Open
The Standard Model cannot explain the dominance of matter over anti-matter in our universe. This imbalance indicates undiscovered physics that violates combined CP symmetry. Many extensions to the Standard Model seek to explain the imbalan…

Systematic and statistical uncertainty evaluation of the HfF$^+$ electron electric dipole moment experiment Open
We have completed a new precision measurement of the electron's electric dipole moment using trapped HfF$^+$ in rotating bias fields. We report on the accuracy evaluation of this measurement, describing the mechanisms behind our systematic…

Experimental Constraint on Axionlike Particles over Seven Orders of Magnitude in Mass Open
We use our recent electric dipole moment (EDM) measurement data to constrain the possibility that the HfF^{+} EDM oscillates in time due to interactions with candidate dark matter axionlike particles (ALPs). We employ a Bayesian analysis m…

Second-Scale Coherence Measured at the Quantum Projection Noise Limit with Hundreds of Molecular Ions Open
Cold molecules provide an excellent platform for quantum information, cold chemistry, and precision measurement. Certain molecules have enhanced sensitivity to beyond standard model physics, such as the electron's electric dipole moment (e…

Precision Test of the Limits to Universality in Few-Body Physics Open
We perform precise studies of two- and three-body interactions near an intermediate-strength Feshbach resonance in ^{39}K at 33.5820(14) G. Precise measurement of dimer binding energies, spanning three orders of magnitude, enables the cons…

Can Three-Body Recombination Purify a Quantum Gas? Open
Three-body recombination in quantum gases is traditionally associated with heating, but it was recently found that it can also cool the gas. We show that in a partially condensed three-dimensional homogeneous Bose gas three-body loss could…

Precision Measurement of the Electron’s Electric Dipole Moment Using Trapped Molecular Ions Open
We describe the first precision measurement of the electron's electric dipole moment (d_{e}) using trapped molecular ions, demonstrating the application of spin interrogation times over 700 ms to achieve high sensitivity and stringent reje…

Observation of Efimov Molecules Created from a Resonantly Interacting Bose Gas Open
We convert a strongly interacting ultracold Bose gas into a mixture of atoms and molecules by sweeping the interactions from resonant to weak. By analyzing the decay dynamics of the molecular gas, we show that in addition to Feshbach dimer…

Collapse and revival of the monopole mode of a degenerate Bose gas in an isotropic harmonic trap Open
We study the monopole (breathing) mode of a finite temperature Bose-Einstein\ncondensate in an isotropic harmonic trap recently developed by Lobser et al.\n[Nat.~Phys., \\textbf{11}, 1009 (2015)]. We observe a nonexponential collapse of\nt…

Bose Polarons in the Strongly Interacting Regime Open
When an impurity is immersed in a Bose-Einstein condensate, impurity-boson interactions are expected to dress the impurity into a quasiparticle, the Bose polaron. We superimpose an ultracold atomic gas of ^{87}Rb with a much lower density …
