Closed-channel parameters of Feshbach resonances
This work investigates how the closed channel of a Feshbach resonance is characterised by experimental observables. Surprisingly, it is found that the two-body observables associated with the Feshbach resonance can be insensitive to the properties of the

Formation of ultracold NaRb Feshbach molecules
We report the creation of ultracold bosonic ^23 Na ^87 Rb Feshbach molecules via magneto-association. By ramping the magnetic field across an interspecies Feshbach resonance (FR), at least 4000 molecules can be produced out of the near degenerate ...

Feshbach resonances in ultracold K(39)
We discover several magnetic Feshbach resonances in collisions of ultracold K(39) atoms, by studying atom losses and molecule formation. Accurate determination of the magnetic-field resonance locations allows us to optimize a quantum collision model for potassium isotopes.

Recently, the transformation from random to chaotic behavior in the statistics of Fano–Feshbach resonances was observed in thulium atoms with rising ensemble temperature.

Magnetic control of ultra-cold 6Li and 174Yb(3P2) atom mixtures with Feshbach resonances
We theoretically evaluate the feasibility to form magnetically-tunable Feshbach molecules in collisions between fermionic ^6 Li atoms and bosonic metastable ^174 Yb( ^3 P _2 ) atoms.

Feshbach spectroscopy of an ultracold Rb-Cs mixture [PDF]
This thesis reports the observation of interspecies Feshbach resonances in an ultracold mixture of Rb and Cs atoms. A versatile combined magnetic and optical potential has been designed and constructed which is capable of bringing both $^{87}\rm{Rb}$ and

Signatures of Superfluidity for Feshbach-Resonant Fermi Gases [PDF]
We consider atomic Fermi gases where Feshbach resonances can be used to continuously tune the system from weak to strong interaction regime, allowing to scan the whole BCS-BEC crossover. We show how a probing field transferring atoms out of the superfluid can be used to detect the onset of the superfluid transition in the high-$T_c$ and BCS regimes ...

Quantum chaos in Feshbach resonances of the ErYb system
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.

Dipolar Bose–Einstein condensation of 168Er and anisotropic expansion dynamics
We report on the realization of Bose–Einstein condensation (BEC) of 168Er atoms in a crossed optical dipole trap. A magneto-optical trap is realized with just one laser driving the narrow-line transition which increases the phase space density and ...
