Universal Threshold Laws for Dipolar Evaporation of Molecular Fermi Gases
Kevin B. Xu, John L. Bohn, Reuben R. W. Wang
Fermi statistics suppress the elastic collisions that rethermalize a Fermi gas during evaporative cooling, creating a fundamental low-temperature bottleneck for producing quantum d…
Limits of Statistical Models of Ultracold Complex Lifetimes
Kevin B. Xu, John L. Bohn
The puzzle of "sticky collisions," in which molecular collision complexes exhibit unexpectedly long lifetimes, remains an unresolved mystery. A central challenge to solving this my…
Collisional relaxation in shielded dipolar molecular gases
Reuben R. W. Wang, John L. Bohn
We discuss the influence of collisions on the dynamics of an ultracold gas whose constituents interact via dipolar forces. This dynamics is governed by the elastic scattering cross…
Ground and excited potential energy surfaces for CaF+Ca interactions and isotope exchange reactions
Dibyendu Sardar, John L. Bohn
We investigate the intermolecular interactions between laser-cooled CaF and Ca, in their ground and excited electronic states, aiming to understand atom-exchange reaction pathways.…
Theory of itinerant collisional spin dynamics in nondegenerate molecular gases
Reuben R. W. Wang, John L. Bohn
We study the fully itinerant dynamics of ultracold but nondegenerate polar molecules with a spin- degree of freedom encoded into two of their electric field dressed rotational…
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…
Confinement-induced field-linked states of ultracold polar molecules
Reuben R. W. Wang, John L. Bohn
We predict the existence of stable bound states between pairs of ultracold diatomic molecules with the aid of a static electric field and 1D harmonic confinement. We focus on colli…
Simulations of evaporation to deep Fermi degeneracy in microwave-shielded molecules
Reuben R. W. Wang, Shrestha Biswas, Sebastian Eppelt +3
In the quest toward realizing novel quantum matter in ultracold molecular gases, we perform a numerical study of evaporative cooling in ultracold gases of microwave-shielded polar…
Hyperfine-to-rotational energy transfer in ultracold atom-molecule collisions
Yi-Xiang Liu, Lingbang Zhu, Jeshurun Luke +7
Energy transfer between different mechanical degrees of freedom in atom-molecule collisions has been widely studied and largely understood. However, systems involving spins remain…
Observation of generalized t-J spin dynamics with tunable dipolar interactions
Annette N. Carroll, Henrik Hirzler, Calder Miller +8
Long-range and anisotropic dipolar interactions profoundly modify the dynamics of particles hopping in a periodic lattice potential. We report the realization of a generalized t-J…
Prospects for thermalization of microwave-shielded ultracold molecules
Reuben R. W. Wang, John L. Bohn
We study anisotropic thermalization in dilute gases of microwave shielded polar molecular fermions. For collision energies above the threshold regime, we find that thermalization i…
Probability distributions of atomic scattering lengths
John L. Bohn, Reuben R. W. Wang
The probability distribution of the real and imaginary parts of atomic scattering lengths are derived, in a two-channel model that allows for inelastic scattering to occur. Whi…
