Dual-Microphone Steerable High-Order Neural Differential Beamformer
Weilong Huang, Emanuël A. P. Habets
Linear arrays of omnidirectional microphones produce beampatterns that are symmetric about the array axis. For these arrays, a beamformer is considered steerable if its beampattern…
Self-limiting electrostriction of a single ion in an ultracold polar gas: From mesoscopic ions to crystalline molecular rings
Ruiren Shi, Saajid Chowdhury, Leon Karpa +1
We investigate the self-assembly of polar molecules around a single ion immersed in an ultracold, dilute two-dimensional molecular gas. The ion aligns and attracts the molecules th…
Trap-induced atom-ion complexes: a time-independent approach
Zhongqi Liang, Ruiren Shi, Jesús Pérez-Ríos
A trapped ion immersed in a neutral bath shows long-lived atom-ion complexes that significantly alter its chemical properties, and, thus the ion stability. In this work, we present…
Direct three-body atom recombination: halogen atoms
Rian Koots, Grace Ding, Jesús Pérez-Ríos
The recombination of halogen atoms has been a research topic in chemical physics for over a century. All theoretical descriptions of atom recombination depend on a two-step assumpt…
Effects of the delocalized charge distribution in trapped ion-atom collisions
Ruiren Shi, Michael Drewsen, Jesús Pérez-Ríos
In the study of ion-atom interactions, the ion often remain trapped during the experiments. However, the effects of the trapping potential of the ion on ion-neutral interactions re…
Ultracold long-range van der Waals Rydberg trimer
Mateo Londoño, Vanessa C. Olaya-Agudelo, Felipe Herrera +1
Rydberg molecules, Rydberg-atom or Rydberg-molecule, are an essential ingredient of cold molecular sciences. However, due to the richness of Rydberg-neutral interactions, new kinds…
Chemistry in a Cryogenic Buffer Gas Cell
Qi Sun, Jinyu Dai, Rian Koots +4
Cryogenic buffer gas sources are ubiquitous for producing cold, collimated molecular beams for quantum science, chemistry, and precision measurements. The molecules are typically p…
Machine learning models for atom-diatom reactions across isotopologues
Daniel Julian, Rian Koots, Jesùs Pérez-Ríos
This work shows that feed-forward neural networks can predict the final ro-vibrational state distributions of inelastic and reactive processes of the reaction of Ca H2 $\righta…
The chemistry of AlF and CaF production in buffer gas sources
X. Liu, W. Wang, S. C. Wright +4
In this work, we explore the role of chemical reactions on the properties of buffer gas-cooled molecular beams. In particular, we focus on scenarios relevant to the formation of Al…
Optical cycling of AlF molecules
Simon Hofsäss, Maximilian Doppelbauer, Sid Wright +5
Aluminium monofluoride (AlF) is a promising candidate for laser cooling and trapping at high densities. We show efficient production of AlF in a bright, pulsed cryogenic buffer gas…
Characterisation of the State and Its Interaction with the State in Aluminium Monofluoride
Maximilian Doppelbauer, Nicole Walter, Simon Hofsäss +7
Recently, we determined the detailed energy level structure of the , and states of AlF that are relevant to laser cooling and trapping experiments. Here, we i…
