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…
Tunable two-component ultracold molecular gases with vibrational shielding
Bijit Mukherjee, MichaÅ Tomza
We propose a method to realize stable, tunable two-component quantum mixtures of ultracold polar molecules. First, we show that a pair of polar molecules in two distinct rovibratio…
Charge Exchange Dynamics in Cold Collisions of CaH and K
Swapnil Patel, Dibyendu Sardar, Jyothi Saraladevi +2
We report the observation of charge-exchange collisions between trapped calcium monohydride molecular ions (CaH) and ultracold potassium atoms (K) in a hybrid ion…
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…
Optical excitation and stabilization of ultracold field-linked tetratomic molecules
Bijit Mukherjee, MichaÅ Tomza
We propose a coherent optical population transfer of weakly bound field-linked (FL) tetratomic molecules (tetramers) to deeper FL bound states using stimulated Raman adiabatic pass…
CaF+CaF interactions in the ground and excited electronic states: implications for collisional losses
Dibyendu Sardar, Marcin Gronowski, MichaÅ 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…
