Dissociation and Decay of Ultra-cold Sodium Molecules [PDF]
, 2003 The dissociation of ultracold molecules is studied by ramping an external magnetic field through a Feshbach resonance. The observed dissociation energy shows non-linear dependence on the ramp speed and directly yields the strength of the atom-molecule coupling. In addition, inelastic molecule-molecule and molecule-atom collisions are characterized.

Collisional decay of 87Rb Feshbach molecules at 1005.8 G [PDF]
Phys. Rev. A 74, 062706 (2006), 2006 We present measurements of the loss-rate coefficients K_am and K_mm caused by inelastic atom-molecule and molecule-molecule collisions. A thermal cloud of atomic 87Rb is prepared in an optical dipole trap. A magnetic field is ramped across the Feshbach resonance at 1007.4 G. This associates atom pairs to molecules. A measurement of the molecule loss at

Equivariant Diffusion for Molecule Generation in 3D [PDF]
International Conference on Machine Learning, 2022 This work introduces a diffusion model for molecule generation in 3D that is equivariant to Euclidean transformations. Our E(3) Equivariant Diffusion Model (EDM) learns to denoise a diffusion process with an equivariant network that jointly operates on ...

Molecule–molecule and atom–molecule collisions with ultracold RbCs molecules [PDF]
New Journal of Physics, 2021 Abstract Understanding ultracold collisions involving molecules is of fundamental importance for current experiments, where inelastic collisions typically limit the lifetime of molecular ensembles in optical traps. Here we present a broad study of optically trapped ultracold RbCs molecules in collisions with one another, in reactive ...

Molecular Characterizations of Anisotropic Mixed-Norm Hardy Spaces and Their Applications
Mathematics, 2021 Let p→∈(0,∞)n be an exponent vector and A be a general expansive matrix on Rn. Let HAp→(Rn) be the anisotropic mixed-norm Hardy spaces associated with A defined via the non-tangential grand maximal function.

Separation of ions with the same charge to mass ratio from a collision experiment [PDF]
Journal of the Serbian Chemical Society, 2000 Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.

Protein synthesis molecule by molecule [PDF]
Genome Biology, 2006 Since the earliest days of molecular biology it has been known that even a seemingly uniform culture of bacteria is made up of cells very different from each other in terms of their levels of a given protein. This individuality has now finally been quantified at single-molecule resolution, as reported in two recent papers.

A generative model for molecule generation based on chemical reaction trees [PDF]
, 2021 Deep generative models have been shown powerful in generating novel molecules with desired chemical properties via their representations such as strings, trees or graphs. However, these models are limited in recommending synthetic routes for the generated molecules in practice. We propose a generative model to generate molecules via multi-step chemical

Evidence for association of triatomic molecule in ultracold $^{23}$Na$^{40}$K and $^{40}$K mixture [PDF]
Nature 602, 229 (2022), 2021 Ultracold assembly of diatomic molecules has enabled great advances in controlled chemistry, ultracold chemical physics, and quantum simulation with molecules. Extending the ultracold association to triatomic molecules will offer many new research opportunities and challenges in these fields.
