Sub-barrier peaks in atom-atom-ion three-body recombination
Fabian Thielemann, Joachim Siemund, Tobias Schaetz +1
Hybrid atom-ion experiments have recently entered the few-partial wave regime in which magnetically tunable Feshbach resonances dominate the three-body loss dynamics. This necessit…
Quantum statistics on atom-ion Feshbach resonances
Joachim Siemund, Fabian Thielemann, Jonathan Grieshaber +5
We investigate three-body recombination in a hybrid atom-ion system consisting of a single trapped Ba ion immersed in a two-component Fermi gas of Li atoms near an atom-ion Fes…
Quantum engineering with ultracold polar molecules using trap-induced resonances
Sakthikumaran Ravichandran, Piotr Kulik, Krzysztof Jachymski
Polar molecules represent a promising platform for quantum simulation and computation protocols. Highly controllable arrays of optical tweezers are now accessible in experiments, a…
Magnetic Feshbach resonances in Ba+Li collisions due to strong spin-orbit coupling
Masato Morita, Joachim Siemund, Wei Wu +8
We report a pronounced dependence of magnetic Feshbach resonance spectra on the initial hyperfine-Zeeman state of Li in ultracold Ba+Li collisions. The measured num…
Exploring atom-ion Feshbach resonances below the s-wave limit
Fabian Thielemann, Joachim Siemund, Daniel von Schoenfeld +5
Revealing the quantum properties of matter requires a high degree of experimental control accompanied by a profound theoretical understanding. At ultracold temperatures, quantities…
