Asymptotic Bound-state Model for Feshbach Resonances [PDF]
Physical Review A, 2010 We present an Asymptotic Bound-state Model which can be used to accurately describe all Feshbach resonance positions and widths in a two-body system. With this model we determine the coupled bound states of a particular two-body system.

Radiative neutron capture: Hauser Feshbach vs. statistical resonances
Physics Letters B, 2017 The radiative neutron capture rates for isotopes of astrophysical interest are commonly calculated on the basis of the statistical Hauser Feshbach (HF) reaction model, leading to smooth and monotonically varying temperature-dependent Maxwellian-averaged ...

Ab initio calculation of the spectrum of Feshbach resonances in NaLi + Na collisions [PDF]
Physical Review A, 2023 We present a combined experimental and theoretical study of the spectrum of magnetically tunable Feshbach resonances in NaLi $(a^3\Sigma^+)$ $+$ Na collisions.

Exploring Ultracold Collisions in ^{6}Li-^{53}Cr Fermi Mixtures: Feshbach Resonances and Scattering Properties of a Novel Alkali-Transition Metal System. [PDF]
Physical Review Letters, 2022 We investigate ultracold collisions in a novel mixture of ^{6}Li and ^{53}Cr fermionic atoms, discovering more than 50 interspecies Feshbach resonances via loss spectroscopy. Building a full coupled-channel model, we unambiguously characterize the ^{6}Li-

Tomography of Feshbach resonance states [PDF]
Science, 2023 Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules. In this work, we present the detection of Feshbach resonances in a benchmark system for strongly interacting and highly anisotropic collisions: molecular hydrogen ions colliding with noble gas atoms ...

Feshbach resonances of large-mass-imbalance Er-Li mixtures [PDF]
Physical Review A, 2021 We report on the experimental observation of Feshbach resonances in large mass-imbalance mixtures of Erbium (Er) and Lithium (Li). All combinations between Er, Er and Li, Li are cooled to temperatures of a few microkelvin, partially by means of ...

A compact and fast magnetic coil for the manipulation of quantum gases with Feshbach resonances. [PDF]
Review of Scientific Instruments, 2021 Cold atom experiments commonly use broad magnetic Feshbach resonances to manipulate the interaction between atoms. In order to induce quantum dynamics by a change in the interaction strength, rapid (∼μs) magnetic field changes over several tens of Gauss ...

Polaritonic quantum matter. [PDF]
NanophotonicsAbstract Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light–matter admixture causes a characteristic frequency‐momentum dispersion shared by all polaritons irrespective of the microscopic nature of material excitations that could entail charge, spin, lattice or orbital ...
