Tunable itinerant spin dynamics with polar molecules Open
Strongly interacting spins underlie many intriguing phenomena and applications ranging from magnetism to quantum information processing. Interacting spins combined with motion display exotic spin transport phenomena, such as superfluidity …

Dynamical Generation of Spin Squeezing in Ultracold Dipolar Molecules Open
We study a bulk fermionic dipolar molecular gas in the quantum degenerate regime confined in a two-dimensional geometry. Using two rotational states of the molecules, we encode a spin 1/2 degree of freedom. To describe the many-body spin d…

Tuning of dipolar interactions and evaporative cooling in a three-dimensional molecular quantum gas Open
Ultracold polar molecules possess long-range, anisotropic, and tunable dipolar interactions, providing the opportunities to probe quantum phenomena inaccessible with existing cold gas platforms. However, experimental progress has been hind…

Resonant collisional shielding of reactive molecules using electric fields Open
Electric field shielding of ultracold molecules Because reactive collisions limit the lifetime of ultracold molecular ensembles, controlling chemical reactivity at ultralow temperatures has been a long-standing goal. Using large electric f…

Dynamical generation of spin squeezing in ultra-cold dipolar molecules Open
We study a bulk fermionic dipolar molecular gas in the quantum degenerate regime confined in a two-dimensional geometry. We consider two rotational states that encode a spin 1/2 degree of freedom. We derive a long-range interacting XXZ mod…

Quantum many-body physics with ultracold polar molecules: Nanostructured potential barriers and interactions Open
We design dipolar quantum many-body Hamiltonians that will facilitate the\nrealization of exotic quantum phases under current experimental conditions\nachieved for polar molecules. The main idea is to modulate both single-body\npotential b…

Thermalization and Sub-Poissonian Density Fluctuations in a Degenerate Molecular Fermi Gas Open
We observe thermalization in the production of a degenerate Fermi gas of polar ^{40}K^{87}Rb molecules. By measuring the atom-dimer elastic scattering cross section near the Feshbach resonance, we show that Feshbach molecules rapidly reach…

Sisyphus Laser Cooling of a Polyatomic Molecule Open
We perform magnetically assisted Sisyphus laser cooling of the triatomic free radical strontium monohydroxide (SrOH). This is achieved with principal optical cycling in the rotationally closed P(N^{''}=1) branch of either the X[over ˜]^{2}…
