Collisionally stable gas of bosonic dipolar ground-state molecules

N Bigagli, C Warner, W Yuan, S Zhang, I Stevenson… - Nature Physics, 2023 - nature.com
Stable ultracold ensembles of dipolar molecules hold great promise for studies of many-
body quantum physics, but high inelastic loss rates have been a long-standing challenge …

Microwave shielding of bosonic NaRb molecules

J Lin, G Chen, M Jin, Z Shi, F Deng, W Zhang… - Physical Review X, 2023 - APS
Recent years have witnessed tremendous progress in creating and manipulating ground-
state ultracold polar molecules. However, the two-body loss regardless of the chemical …

Viscous dynamics of a quenched trapped dipolar Fermi gas

RRW Wang, JL Bohn - Physical Review A, 2023 - APS
We consider collective motion and damping of dipolar Fermi gases in the hydrodynamic
regime. We investigate the trajectories of collective oscillations—here dubbed “weltering” …

Anisotropic acoustics in dipolar Fermi gases

RRW Wang, JL Bohn - Physical Review A, 2023 - APS
We consider plane wave modes in ultracold, but not quantum degenerate, dipolar Fermi
gases in the hydrodynamic limit. Longitudinal waves present anisotropies in both the speed …

Prospects for thermalization of microwave-shielded ultracold molecules

RRW Wang, JL Bohn - Physical Review Research, 2024 - APS
Toward more efficient schemes for achieving deeply degenerate molecular Fermi gases, we
study anisotropic thermalization in dilute gases of microwave shielded polar molecular …

Physics-guided weak-form discovery of reduced-order models for trapped ultracold hydrodynamics

RRW Wang, D Messenger - arXiv preprint arXiv:2406.07519, 2024 - arxiv.org
We study the relaxation of a highly collisional, ultracold but nondegenerate gas of polar
molecules. Confined within a harmonic trap, the gas is subject to fluid-gaseous coupled …

Viscous damping in weltering motion of trapped hydrodynamic dipolar Fermi gases

RRW Wang, JL Bohn - arXiv preprint arXiv:2306.00250, 2023 - arxiv.org
We consider collective motion and damping of dipolar Fermi gases in the hydrodynamic
regime. We investigate the trajectories of collective oscillations--here dubbed``weltering'' …
