Diatomic molecular anions of alkali-metal and alkaline-earth-metal atoms
Sana Akkari, Hela Ladjimi, Wissem Zrafi +3
Studies of anions are inherently more challenging than investigations of neutrals and cations because of the diffuse and weakly bound character of an anionic electron. Here, we pre…
Infrared absorption spectroscopy of a single polyatomic molecular ion
Zhenlin Wu, Tim Duka, Mariano Isaza-Monsalve +8
Absorption spectroscopy is a fundamental tool for probing molecular structure. However, performing absorption spectroscopy on individual molecules is challenging due to the low sig…
Ultracold high-spin -state polar molecules for new physics searches
Alessio Ciamei, Adam Koza, Marcin Gronowski +1
We propose high-spin -state polar molecules assembled from ultracold atoms to probe charge-parity violating physics beyond the Standard Model. We identify YbCr as a prime candid…
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…
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…
Interactions and cold collisions of AlF in the ground and excited electronic states with He
Sangami Ganesan-Santhi, Matthew D. Frye, Marcin Gronowski +1
Aluminium monofluoride (AlF) is a promising candidate for laser cooling and the production of dense ultracold molecular gases, thanks to its relatively high chemical stability and…
