Bose-Einstein Condensation of Erbium

open access: yes, 2012
We report on the achievement of Bose-Einstein condensation of erbium atoms and on the observation of magnetic Feshbach resonances at low magnetic field. By means of evaporative cooling in an optical dipole trap, we produce pure condensates of $^{168}$Er,

Efimov Physics and the Three-Body Parameter within a Two-Channel Framework

open access: yes, 2012
We calculate shallow three-body bound states in the universal regime, defined by Efimov, with inclusion of both scattering length and effective range parameters.

Feshbach resonances in ultracold 85Rb-87Rb and 6Li-87Rb mixtures

open access: yes, 2008
We present an analysis of experimentally accessible magnetic Feshbach resonances in ultra-cold hetero-nuclear 85Rb-87Rb and 6Li-87Rb mixtures. Using recent experimental measurements of the triplet scattering lengths for 6Li-87Rb and 7Li-87Rb mixtures and

Fano-Feshbach resonances in two-channel scattering around exceptional points

open access: yes, 2014
It is well known that in open quantum systems resonances can coalesce at an exceptional point, where both the energies {\em and} the wave functions coincide. In contrast to the usual behaviour of the scattering amplitude at one resonance, the coalescence

Analysis of light scattering off photonic crystal slabs in terms of Feshbach resonances

open access: yes, 2012
Techniques to deal with Feshbach resonances are applied to describe resonant light scattering off one dimensional photonic crystal slabs. Accurate expressions for scattering amplitudes, free of any fitting parameter, are obtained for isolated as well as ...

Quantum defect theory description of weakly bound levels and Feshbach resonances in LiRb

open access: yesNew Journal of Physics, 2015
The multichannel quantum defect theory (MQDT) in combination with the frame transformation (FT) approach is applied to model the Fano–Feshbach resonances measured for ^7 Li ^87 Rb and ^6 Li ^87 Rb Marzok et al (2009 Phys. Rev. A http://dx.doi.org/10.1103/

Heating and atom loss during upward ramps of Feshbach resonance levels in Bose-Einstein condensates

open access: yes, 2004
The production of pairs of fast atoms leads to a pronounced loss of atoms during upward ramps of Feshbach resonance levels in dilute Bose-Einstein condensates.
