A dynamical process of optically trapped singlet ground state 85Rb133Cs molecules produced via short-range photoassociation
文献情報
We investigate the dynamical process of optically trapped X1Σ+ (v′′ = 0) state 85Rb133Cs molecules distributed in J′′ = 1 and J′′ = 3 rotational states. The considered molecules, formed from short-range photoassociation of mixed cold atoms, are subsequently confined in a crossed optical dipole trap. Based on a phenomenological rate equation, we provide a detailed study of the dynamics of 85Rb133Cs molecules during the loading and holding processes. The inelastic collisions of 85Rb133Cs molecules in the X1Σ+ (v′′ = 0, J′′ = 1 and J′′ = 3) states with ultracold 85Rb (or 133Cs) atoms are measured to be 1.0 (2) × 10−10 cm3 s−1 (1.2 (3) × 10−10 cm3 s−1). Our work provides a simple and generic procedure for studying the dynamical process of trapped cold molecules in the singlet ground states.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
