Observation of molecules produced from a Bose-Einstein condensate

, 2004
Molecules are created from a Bose-Einstein condensate of atomic 87Rb using a Feshbach resonance. A Stern-Gerlach field is applied, in order to spatially separate the molecules from the remaining atoms. For detection, the molecules are converted back into

Controlling a magnetic Feshbach resonance with laser light

, 2009
The capability to tune the strength of the elastic interparticle interaction is crucial for many experiments with ultracold gases. Magnetic Feshbach resonances are a tool widely used for this purpose, but future experiments would benefit from additional ...

Universal Quantum Dynamics of Bose Polarons

Physical Review X
Predicting the emergent properties of impurities immersed in a quantum bath is a fundamental challenge that can defy quasiparticle treatments. Here, we measure the spectral properties and real-time dynamics of mobile impurities injected into a weakly ...

An analytic approach to probability tables for the unresolved resonance region

EPJ Web of Conferences, 2017
The Unresolved Resonance Region (URR) connects the fast neutron region with the Resolved Resonance Region (RRR). The URR is problematic since resonances are not resolvable experimentally yet the fluctuations in the neutron cross sections play a ...

Efimov states near a Feshbach resonance and the limits of van der Waals universality at finite background scattering length

, 2018
We calculate the spectrum of three-body Efimov bound states near a Feshbach resonance within a model which accounts both for the finite range of interactions and the presence of background scattering.

Magnetic field dependent interactions in an ultracold Li–Yb(3P2) mixture

New Journal of Physics, 2015
Magnetic Feshbach resonances have allowed great success in the production of ultracold diatomic molecules from bi-alkali mixtures, but have so far eluded observation in mixtures of alkali and alkaline-earth-like atoms. Inelastic collisional properties of

Induced two-body scattering resonances from a square-well potential with oscillating depth

EPJ Web of Conferences, 2016
In systems of ultracold atoms, pairwise interactions can be resonantly enhanced by a new mechanism which does not rely upon a magnetic Feshbach resonance.

Anisotropy induced Feshbach resonances in a quantum dipolar gas of magnetic atoms

, 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.

Nonequilibrium dynamics and atom-pair coherence in strongly interacting Bose-Fermi mixtures

Physical Review Research
Theoretical treatments of nonequilibrium dynamics in strongly interacting Bose-Fermi mixtures are complicated by the inherent non-Gaussian nature of the vacuum two-body physics, invalidating the typical Hartree-Fock-Bogoliubov approximation.
