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

open access: yesNew 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

Closed-channel parameters of Feshbach resonances

open access: yesSciPost Physics
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

Feshbach resonances in Cesium at Ultra-low Static Magnetic Fields [PDF]

open access: yes, 2012
We have observed Feshbach resonances for 133Cs atoms in two different hyperfine states at ultra-low static magnetic fields by using an atomic fountain clock.

Bogoliubov theory of Feshbach molecules in the BEC-BCS crossover [PDF]

open access: yes, 2006
We present the Bogoliubov theory for the Bose-Einstein condensation of Feshbach molecules in a balanced Fermi mixture. Because the Bogoliubov theory includes (Gaussian) fluctuations, we can in this manner accurately incorporate both the two-body and many-

Imbalanced Feshbach-resonant Fermi gases [PDF]

open access: yesReports on Progress in Physics, 2010
We present an overview of recent developments in species-imbalanced ("polarized") Feshbach-resonant Fermi gases. We summarize the current status of thermodynamics of these systems in terms of a phase diagram as a function of the Feshbach resonance detuning, polarization and temperature. We review instabilities of the s-wave superfluidity across the BEC-

Observation of interspecies Feshbach resonances in an ultracold Rb-Cs mixture

open access: yes, 2008
We report on the observation of interspecies Feshbach resonances in an ultracold, optically trapped mixture of Rb and Cs atoms. In a magnetic field range up to 300 G we find 23 interspecies Feshbach resonances in the lowest spin channel and 2 resonances ...

Dysprosium dipolar Bose-Einstein condensate with broad Feshbach resonances [PDF]

open access: yes, 2018
We produce Bose-Einstein condensates of $^{162}\mathrm{Dy}$ atoms employing an innovative technique based on a resonator-enhanced optical trap that allows efficient loading from the magneto-optical trap.

Observation of Broad d-Wave Feshbach Resonances with a Triplet Structure. [PDF]

open access: yesPhysical Review Letters, 2017
High partial-wave (l≥2) Feshbach resonance (FR) in an ultracold mixture of ^{85}Rb-^{87}Rb atoms is investigated experimentally aided by a partial-wave insensitive analytic multichannel quantum-defect theory.

An efficient nonlinear Feshbach engine

open access: yesNew Journal of Physics, 2018
We investigate a thermodynamic cycle using a Bose–Einstein condensate (BEC) with nonlinear interactions as the working medium. Exploiting Feshbach resonances to change the interaction strength of the BEC allows us to produce work by expanding and ...
