Phase protection of Fano-Feshbach resonances [PDF]
Nature Communications, 2020 The lifetime of decaying quantum states has been thought to depend on the strength of the coupling causing the decay. Here the authors demonstrate that quantum mechanical interference can dominate this process, observing Fano-Feshbach resonance lifetimes

Feshbach resonances in the F + H2O → HF + OH reaction [PDF]
Nature Communications, 2020 Feshbach resonances are transiently trapped states along a reaction coordinate, providing a probe to the reaction’s potential energy surface (PES) but difficult to analyze in polyatomic systems. Here the authors identify Feshbach resonances in a reacting

Feshbach Resonances in p-Wave Three-Body Recombination within Fermi-Fermi Mixtures of Open-Shell ^{6}Li and Closed-Shell ^{173}Yb Atoms [PDF]
Physical Review X, 2020 We report on the observation of magnetic Feshbach resonances in a Fermi-Fermi mixture of ultracold atoms with extreme mass imbalance and on their unique p-wave dominated three-body recombination processes. Our system consists of open-shell alkali-metal ^{

Attosecond photoionization delays in the vicinity of molecular Feshbach resonances. [PDF]
Sci Adv, 2023 Temporal delays extracted from photoionization phases are currently determined with attosecond resolution by using interferometric methods. Such methods require special care when photoionization occurs near Feshbach resonances due to the interference ...

Magnetic Feshbach resonances in collisions of 23Na40K with 40K [PDF]
New Journal of Physics, 2021 We present measurements of more than 80 magnetic Feshbach resonances in collisions of ultracold ^23 Na ^40 K with ^40 K. We assign quantum numbers to a group of low-field resonances and show that they are probably due to long-range states of the ...

Random Matrix Theory Analysis of a Temperature-Related Transformation in Statistics of Fano–Feshbach Resonances in Thulium Atoms [PDF]
Entropy, 2020 Recently, the transformation from random to chaotic behavior in the statistics of Fano–Feshbach resonances was observed in thulium atoms with rising ensemble temperature.

Quantum chaos in Feshbach resonances of the ErYb system [PDF]
New Journal of Physics, 2020 We investigate ultracold magnetic-field-assisted collisions in the so far unexplored ErYb system. The nonsphericity of the Er atom leads to weakly anisotropic interactions that provide the mechanism for Feshbach resonances to emerge.

Anisotropy-induced Feshbach resonances in a quantum dipolar gas of highly magnetic atoms. [PDF]
Phys Rev Lett, 2012 We explore the anisotropic nature of Feshbach resonances in the collision between ultracold magnetic submerged-shell dysprosium atoms, which can only occur due to couplings to rotating bound states.

Feshbach resonances in potassium Bose-Bose mixtures [PDF]
Physical Review A, 2018 We present a detailed study of the scattering properties of ultracold mixtures of bosonic potassium atoms. We locate 20 previously unobserved Feshbach resonances in isotopic 39K-41K mixtures.

Mott-insulator-aided detection of ultra-narrow Feshbach resonances [PDF]
SciPost Physics, 2018 We report on the detection of extremely narrow Feshbach resonances by employing a Mott-insulating state for cesium atoms in a three-dimensional optical lattice.
