Isomer- and state-dependent ion-molecule reactions between Coulomb-crystallised Ca ions and 1,2-dichloroethene
Lei Xu, Richard Karl, Jutta Toscano +1
We report a systematic investigation of isomer- and state-dependent reactions between Coulomb-crystallised laser-cooled Ca ions and \emph{cis/trans}-1,2-dichloroethene (DCE) is…
Automation in quantum logic experiments with cold molecular ions
Richard Karl, Meissa Diouf, Aleksandr Shlykov +2
Modern experiments with cold molecular ions have reached a high degree of complexity requiring frequent sample preparation, state initialization and protocol execution while demand…
Control of chemical reactions in radiofrequency ion traps
Prerna Paliwal, Jutta Toscano, Stefan Willitsch
Over the past years, radiofrequency ion traps have become an attractive platform for studying chemical reactions as they enable a high degree of control over ion-molecule dynamics.…
The role of spectator modes in the quantum-logic spectroscopy of single trapped molecular ions
Mikolaj Roguski, Aleksandr Shlykov, Ziv Meir +1
Quantum-logic spectroscopy has become an increasingly important tool for the state detection and readout of trapped atomic and molecular ions which do not possess easily accessible…
Ion counting and temperature determination of Coulomb-crystallized laser-cooled ions in traps using convolutional neural networks
Yanning Yin, Stefan Willitsch
Coulomb crystals -- ordered structures of cold ions confined in ion traps -- find applications in a variety of research fields. The number and temperature of the ions forming the C…
