Feshbach resonances in ultracold Rb

CL Blackley, CR Le Sueur, JM Hutson… - Physical Review A …, 2013 - APS
We present 17 experimentally confirmed Feshbach resonances in optically trapped 85 Rb.
Seven of the resonances are in the ground-state channel (f, mf)=(2,+ 2)+(2,+ 2) and nine are …

Feshbach resonances, molecular bound states, and prospects of ultracold-molecule formation in mixtures of ultracold K and Cs

HJ Patel, CL Blackley, SL Cornish, JM Hutson - Physical Review A, 2014 - APS
We consider the possibilities for producing ultracold mixtures of K and Cs and forming KCs
molecules by magnetoassociation. We carry out coupled-channel calculations of the …

Magnetic levitation for effective loading of cold cesium atoms in a crossed dipole trap

Y Li, G Feng, R Xu, X Wang, J Wu, G Chen, X Dai, J Ma… - Physical Review A, 2015 - APS
We report a detailed study of effective magnetically levitated loading of cold atoms in a
crossed dipole trap: an appropriate magnetic field gradient precisely compensates for the …

Optical runaway evaporation for the parallel production of multiple Bose-Einstein condensates

AB Deb, T McKellar, N Kjærgaard - Physical Review A, 2014 - APS
