Ultracold molecules in the absolute ground state
K. H. Leung, E. Tiberi, B. Iritani +3
We report efficient all-optical creation of an ultracold gas of alkaline-earth-metal dimers, , in their absolute ground state. Starting with weakly bound singlet mo…
Precise study of asymptotic physics with subradiant ultracold molecules
B. H. McGuyer, M. McDonald, G. Z. Iwata +4
Weakly bound molecules have physical properties without atomic analogues, even as the bond length approaches dissociation. In particular, the internal symmetries of homonuclear dia…
Searching for New Fundamental Interactions via Isotopic Shifts in Molecular Lattice Clocks
E. Tiberi, M. Borkowski, B. Iritani +2
Precision measurements with ultracold atoms and molecules are primed to probe beyond-the-Standard Model physics. Isotopologues of homonuclear molecules are a natural testbed for ne…
Transition strength measurements to guide magic wavelength selection in optically trapped molecules
K. H. Leung, I. Majewska, H. Bekker +5
Optical trapping of molecules with long coherence times is crucial for many protocols in quantum information and metrology. However, the factors that limit the lifetimes of the tra…
Photodissociation of ultracold diatomic strontium molecules with quantum state control
M. McDonald, B. H. McGuyer, F. Apfelbeck +4
Chemical reactions at ultracold temperatures are expected to be dominated by quantum mechanical effects. Although progress towards ultracold chemistry has been made through atomic…
Control of Optical Transitions with Magnetic Fields in Weakly Bound Molecules
B. H. McGuyer, M. McDonald, G. Z. Iwata +3
In weakly bound diatomic molecules, energy levels are closely spaced and thus more susceptible to mixing by magnetic fields than in the constituent atoms. We use this effect to con…
Accurate Determination of Blackbody Radiation Shifts in a Strontium Molecular Lattice Clock
B. Iritani, E. Tiberi, W. Skomorowski +3
Molecular lattice clocks enable the search for new physics, such as fifth forces or temporal variations of fundamental constants, in a manner complementary to atomic clocks. Blackb…
A terahertz vibrational molecular clock with systematic uncertainty at the level
K. H. Leung, B. Iritani, E. Tiberi +4
Neutral quantum absorbers in optical lattices have emerged as a leading platform for achieving clocks with exquisite spectroscopic resolution. However, the studies of these clocks…
Molecular lattice clock with long vibrational coherence
S. S. Kondov, C. -H. Lee, K. H. Leung +4
Atomic lattice clocks have spurred numerous ideas for tests of fundamental physics, detection of general relativistic effects, and studies of interacting many-body systems. On the…
Crossover from the Ultracold to the Quasiclassical Regime in State-Selected Photodissociation
S. S. Kondov, C. -H. Lee, M. McDonald +4
Processes that break molecular bonds are typically observed with molecules occupying a mixture of quantum states and successfully described with quasiclassical models, while a few…
Control of Ultracold Photodissociation with Magnetic Fields
M. McDonald, I. Majewska, C. -H. Lee +4
Photodissociation of a molecule produces a spatial distribution of photofragments determined by the molecular structure and the characteristics of the dissociating light. Performin…
Nonadiabatic Effects in Ultracold Molecules via Anomalous Linear and Quadratic Zeeman Shifts
B. H. McGuyer, C. B. Osborn, M. McDonald +4
Anomalously large linear and quadratic Zeeman shifts are measured for weakly bound ultracold Sr molecules near the intercombination-line asymptote. Nonadiabatic Coriolis…
Experimental and Theoretical Investigation of the Crossover from the Ultracold to the Quasiclassical Regime of Photodissociation
I. Majewska, S. S. Kondov, C. -H. Lee +4
At ultralow energies, atoms and molecules undergo collisions and reactions that are best described in terms of quantum mechanical wave functions. In contrast, at higher energies th…
