Collisional properties of weakly bound heteronuclear dimers
B. Marcelis, S. J. J. M. F. Kokkelmans, G. V. Shlyapnikov +1
We consider collisional properties of weakly bound heteronuclear molecules (dimers) formed in a two-species mixture of atoms with a large mass difference. We focus on dimers contai…
Total control over ultracold interactions via electric and magnetic fields
Bout Marcelis, Boudewijn Verhaar, Servaas Kokkelmans
The scattering length is commonly used to characterize the strength of ultracold atomic interactions, since it is the leading parameter in the low-energy expansion of the scatterin…
Fermionic superfluidity with positive scattering length
Bout Marcelis, Servaas Kokkelmans
Superfluidity in an ultracold Fermi gas is usually associated with either a negative scattering length, or the presence of a two-body bound state. We show that none of these ingred…
Formation of fermionic molecules via interisotope Feshbach resonances
E. G. M. v. Kempen, B. Marcelis, S. J. J. M. F. Kokkelmans
We perform an analysis of recent experimental measurements and improve the lithium interaction potentials. For Li a consistent description can be given. We discuss theoretical…
Feshbach resonances with large background scattering length: interplay with open-channel resonances
B. Marcelis, E. G. M. van Kempen, B. J. Verhaar +1
Feshbach resonances are commonly described by a single-resonance Feshbach model, and open-channel resonances are not taken into account explicitly. However, an open-channel resonan…
